Title:Effect of crack template structure morphology on electromagnetic shielding efficiency and visual performance of metal mesh optical window
Author Full Names:Yang, Liqing(1); Guan, Yongmao(1,2); Gao, Fei(1); Wan, Rui(1); Wang, Pengfei(1)Source Title:Results in EngineeringLanguage:EnglishDocument Type:Journal article (JA)Abstract:Electromagnetic shielding optical windows are crucial for protecting photoelectric detection and imaging systems. The template used in metal mesh fabrication significantly affects the electromagnetic shielding and visual performance of these windows. This study explores the preparation of crack templates with varying structural parameters by adjusting the precursor solution. Four different acrylic resin colloids were prepared using water, ethylene glycol, glycerol, and N-methylpyrrolidone (NMP), leading to the creation of four mask templates (DP1–DP4). The morphology and structural characteristics of the templates were analyzed using optical and laser confocal microscopy. DP1, made with water, exhibited the highest edge warping (1.5 μm), whereas DP4, using ethylene glycol and glycerol, showed the least warping (0.3 μm). Infrared spectroscopy revealed that hydrogen bonding in the solvents influenced crack formation, resulting in narrower cracks and smaller periods. Copper meshes were deposited using these templates, with DP1- and DP4-mesh showing average transmittances of 80.2 % and 84.5 %, respectively, across 380–800 nm. Electromagnetic shielding efficiency exceeded 15 dB between 1 and 18 GHz, with DP1-mesh reaching 29 dB at 1 GHz. However, DP1-mesh's larger lines reduced light transmittance, likely due to increased edge warping enhancing line connectivity and reducing breakage. ? 2025 The AuthorsAffiliations:(1) State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences (CAS), Xi'an; 710119, China; (2) Center of Materials Science and Optoelectronics Engineering, University of Chinese Academy of Sciences, Beijing; 100049, ChinaPublication Year:2025Volume:25Article Number:103888DOI Link:10.1016/j.rineng.2024.103888數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20250317708234 -

However, current systems face limitations in X-ray emission modulation and high-precision timing detection. To meet the high-frequency transmission demands of space missions, we developed a pulsed X-ray emission source capable of high-frequency modulation. Additionally, we identified specific scintillators with distinct advantages for different transmission frequency ranges, allowing for performance optimization.

Title:Fluorescence temperature dependent behaviors of Eu3+/Mn4+ co-doping cubic and hexagonal ZnO-TiO2 compounds: Application in high sensitive optical thermometers
Author Full Names:Sun, Chengmei(1); Xu, Chengcheng(1); Ren, Wenzhen(2); Hu, Fengya(1); Yuan, Jun(1); Wang, Qingru(1); Xie, Yanru(1); Wang, Kai(1); Zhang, Dong(1)Source Title:Journal of Alloys and CompoundsLanguage:EnglishDocument Type:Journal article (JA)Abstract:ZnTiO3:Eu3+,Mn4+ phosphors with hexagonal and cubic structure are synthesized by solvothermal method. The structure of ZnTiO3 depends on precursors and the annealing temperature. Inverse spinel Zn2TiO4 phase reveals the highest thermostability compared with cubic ZnTiO3 and hexagonal ZnTiO3 phases. The different phases of ZnTiO3 crystals exhibit different photoluminescence properties. The forbidden transition of 4A2g→2T2g for Mn4+ is observed in Zn2TiO4 and hexagonal ZnTiO3 (h-ZnTiO3) due to the decreased symmetry. The zero photon line (ZPL) assigned to 2Eg→4A2g transition of Mn4+ is absent in all type ZnTiO3 phases. A sharp emission peak at 714 nm assigned to ν6 (Stokes emission) mode of Mn4+ in h-ZnTiO3 is present when the temperature was below 270 K, and increases sharply in intensity with the temperature decreasing. The similar PL spectra of cubic ZnTiO3 and Zn2TiO4 co-doped with Eu3+ and Mn4+ show a wide emission band composed of Stokes and anti-Stokes modes. The calculated nephelauxetic parameter increases from 0.84 to 1.03 and 1.18 for Mn4+ in h-ZnTiO3, cubic ZnTiO3 and Zn2TiO4, respectively, indicating the covalency decreasing, which causes the red shift of ZPL in h-ZnTiO3. The Mn4+ emissions show stronger temperature dependence than that of Eu3+, especially for that in h-ZnTiO3 matrix. Based on the fluorescence intensity ratio between IEu3+ and IMn4+, the highest relative temperature sensitivity of 2.46 %K?1 is observed in cubic ZnTiO3 (c-ZnTiO3) and Zn2TiO4. Under the excitation at 550 nm, the highest relative sensitivity of 2.9 %K?1 is achieved in c- and h-ZnTiO3 mixed phases. ? 2024 Elsevier B.V.Affiliations:(1) School of Physical Science and Information Technology, Shandong Key Lab. of Optical Communication Science and Technology, Liaocheng University, Liaocheng; 252059, China; (2) State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi'an; 710119, ChinaPublication Year:2025Volume:1010Article Number:177374DOI Link:10.1016/j.jallcom.2024.177374數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20244617354185 -

Employing this method, we successfully fabricated a large-area poly(sulfur-random-(1,3-diisopropenylbenzene)) (S-r-DIB) microlens array (MLA) component. Each micro-concave spherical surface was crafted with a single fs laser pulse, serving as a micro-concave lens surface. We achieved a quasi-periodic MLA sample with over 2 × 105 micro-lenslets within a 10 mm × 10 mm footprint. Additionally, precise locating of laser pulse irradiation enabled us to create a hexagonal MLA with a filling factor over 37 %. Morphological investigations and imaging tests confirmed the adequate surface quality of the fabricated components, with its uniformity revealed by the virtual foci grid in near infrared region. To elucidate the forming conditions and mechanisms, we studied the evolution of surface morphology under various laser irradiation conditions. Laser induced damage thresholds of S70-r-DIB30 were experimentally determined for both 800 nm and 400 nm wavelengths under single- and multi-pulse irradiation scenarios. We identified the optimal fabrication fluence window as 115–205 mJ/cm2 with 800 nm single-pulse irradiation. The bandgap of the S70-r-DIB30 was estimated as 2.06 eV, and energy band analysis confirmed distinctions in ablation morphology. Furthermore, we investigated sub-surface morphology evolution using orthogonal ultrafast pump–probe imaging, revealing diversity compared to traditional inorganic and polymeric optical materials due to differing absorption and etching mechanisms. The elastic wave velocity of 3.2 km/s in this ChP and etching velocity of 0.7 μm/pulse were experimentally determined. These findings deepen our understanding of ChP material interaction with fs lasers, offering insights for potential applications such as surface engineering, substrate cutting, and micro-structure formation. ? 2024Affiliations:(1) Key Laboratory of Light Field Manipulation and Information Acquisition, Ministry of Industry and Information Technology, Shaanxi Key Laboratory of Optical Information Technology, Shaanxi Basic Discipline (Liquid Physics) Research Center, School of Physical Science and Technology, Northwestern Polytechnical University, Xi'an; 710129, China; (2) State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi'an; 710119, ChinaPublication Year:2025Volume:181Article Number:111679DOI Link:10.1016/j.optlastec.2024.111679數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20243516936355 -

Title:Bulk damage growth characteristics and ultrafast diagnosis of fluoride-containing phosphate glasses induced by 355-nm laser
Author Full Names:Li, Shengwu(1,2); Jiang, Yong(3,4); Wan, Rui(1); Wang, Pengfei(1)Source Title:Optics and Laser TechnologyLanguage:EnglishDocument Type:Journal article (JA)Abstract:To comprehensively reveal the influence regularity of different glass melting temperatures on the ultraviolet (UV) laser-induced damage resistance of fluoride-containing phosphate glasses, the initial bulk damage, damaged growth, and dynamic behaviors of both fundamental-frequency (1ω) absorptive and third-harmonic-frequency (3ω) transparent fluoride-containing phosphate glasses are explored utilizing the time-resolved pump–probe shadowgraph technique. A low-temperature (1000 °C) glass melting process resulted in an increase in the absorption coefficient at 355 nm and decrease in the optical bandgap for the 1ω absorptive glass. The produced 1ω absorptive glass was subjected to higher shock pressure and shock temperature on the rear surface after a single-pulse laser irradiation, and had a more serious filamentation damage accompanied by a funnel-shape morphology. With the subsequent multiples irradiation, the initial bulk damage area increased exponentially with a growth coefficient of 0.72. The corresponding exponential growth coefficient for the counterpart 1ω absorptive glass melted at a high temperature (1200 °C) was only 0.32 due to its slight initial bulk damage. In contrast, for the 3ω transparent glass, the high-temperature (1200 °C) melting process led to a larger initial bulk damage area and largest exponential growth coefficient of 0.91, 1.1 times that of the 3ω transparent glass melted at a low temperature (1000 °C). They exhibited wave-packed damaged morphologies extending from the rear surface into the glass body. The melting temperatures exhibited the opposite influence regularity for these two investigated fluoride-containing phosphate glasses. The high-temperature (1200 °C) melting process favored the improvement in UV laser-induced damage resistance of the 1ω absorptive glass, as evidenced by the higher UV laser-induced damage threshold and lower damage growth coefficient, while the low-temperature (1000 °C) melting process exerted similar effects on the 3ω transparent glass. ? 2024 Elsevier LtdAffiliations:(1) State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences (CAS), Shaanxi, Xi'an; 710119, China; (2) State Key Laboratory of Laser Interaction with Matter, Northwest Institute of Nuclear Technology, Shaanxi, Xi'an; 710024, China; (3) School of Science, Southwest University of Science and Technology, Mianyang; 621010, China; (4) Joint Laboratory for Extreme Conditions Matter Properties, Southwest University of Science and Technology, Mianyang; 621010, ChinaPublication Year:2025Volume:182Article Number:112222DOI Link:10.1016/j.optlastec.2024.112222數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20244917469617 -

Using the power of the ?1st comb line (?1st represents the first comb tooth on the left side of the pump laser) as an error signal, the pump laser frequency is auto-tuned to ensure frep locked at an optimal level. After injection locking for 2 h, the single-sideband (SSB) phase noise of the closed-loop locked frep decreases by 20 dB compared with the open-loop locked frep within the offset frequency range of 20 Hz to 30 kHz. After locking one and a half hours, the Allan deviation of the closed-loop locked frep reaches 1.8 × 10?13@0.1 s, which improves by three orders of magnitude. The experimental results prove the feasibility of the optical closed-loop injection technology for long-term frep stabilization.

To solve this problem, a cascade SPR sensor with Ag/Au coating is proposed to measure refractive index (RI) and pH value. In this paper, coreless optical fiber is used as the sensor probe, and Ag/Au are coated on its surface by a magnetron sputtering method. The two sensing channels of this cascade sensor are independent of each other and have a wide parameter detection range. The effects of sensor length and coating time on the performance of the sensor were investigated, and the optimal sensor length and coating time were determined. The experimental results show that the maximum refractive index sensitivity is 3888.6 nm /RIU in the RI range of 1.333–1.385, and the maximum pH sensitivity is 38.01 nm/pH in the pH range of 3.15–8.86. The sensor has the advantages of strong stability and high integration and has a good application prospect in the fields of biosensing and environmental detection. ? 2024Affiliations:(1) State Key Laboratory of Metastable Materials Science & Technology and Key Laboratory for Microstructural Material Physics of Hebei Province, School of Science, Yanshan University, Qinhuangdao; 066004, China; (2) State Key Laboratory of Metastable Materials Science and Technology, Yanshan University, Qinhuangdao; 066004, China; (3) State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences (CAS), Xi'an; 710119, ChinaPublication Year:2025Volume:180Article Number:111452DOI Link:10.1016/j.optlastec.2024.111452數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20242816693160 -

Previous methods mainly focused on the condition of complete polarization conversion, restricting the application range of metasurface polarization multiplexing. Here, we proposed a generalized framework of phase manipulation for the metasurface polarization optics, which can realize independent phase control and arbitrary energy distribution of different polarization channels for the arbitrary polarization conversion efficiency. Based on this principle, we experimentally demonstrate tripolarization-channel wave-front control for the arbitrary polarization state (elliptical, circular, and linear). The arbitrary energy distribution of different polarization channels has been achieved via varying the polarization conversion efficiency. The proposed framework significantly improves the performance of metasurface in the polarization multiplexing and energy distribution, and expands the application scope of metasurface in the polarization optics. ? 2025 American Physical Society.Affiliations:(1) State Key Laboratory of Transient Optics and Photonics, Xi'An Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi'an; 710119, China; (2) National Laboratory of Solid State Microstructures, Key Laboratory of Intelligent Optical Sensing and Manipulations, Jiangsu Key Laboratory of Artificial Functional Materials, College of Engineering and Applied Sciences, Nanjing University, Nanjing; 210093, China; (3) University of Chinese Academy of Sciences, Beijing; 100049, ChinaPublication Year:2025Volume:134Issue:2Article Number:023803DOI Link:10.1103/PhysRevLett.134.023803數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20250317701285 -

Ulrich(5,6,7,8); Gao, Peng(1,2,3)Source Title:Laser and Photonics ReviewsLanguage:EnglishDocument Type:Article in PressAbstract:Optical sectioning structured illumination microscopy (OS-SIM) is a fast, minimally invasive 3D imaging technique that has found widespread application in the biosciences. It is based on sample illumination with several illumination fringe patterns featuring distinct mutual phase shifts, from which an axially sectioned image is reconstructed. Its optical sectioning capability is commonly attributed to the attenuation of the fringe modulation of light collected from planes displaced from the focal plane. However, in addition to this effect, which is governed solely by the detection optics, optical sectioning can be further enhanced by confining the fringe modulation axially via partially coherent illumination (PCI). To establish guidelines for optimal illumination field shaping, both theoretically and experimentally are investigated, the optical sectioning strength of OS-SIM upon variation of the two key parameters, modulation period and angular spectrum of the incident illumination. By using PCI with OS-SIM, nearly fivefold and 1.4-fold enhanced axial resolution have achieved for scattering (non-fluorescent) and fluorescent samples, respectively. This work elucidates the optical sectioning mechanism of OS-SIM and provides a perspective for further optimization. ? 2025 Wiley-VCH GmbH.Affiliations:(1) School of Physics, Xi'dian University, Xi'an; 710071, China; (2) Key Laboratory of Optoelectronic Perception of Complex Environment, Ministry of Education, Xi'an; 710071, China; (3) Engineering Research Center of Information Nanomaterials, Universities of Shaanxi Province, Xi'an; 710071, China; (4) State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi'an; 710119, China; (5) Institute of Applied Physics, Karlsruhe Institute of Technology, Karlsruhe; 76049, Germany; (6) Institute of Nanotechnology, Karlsruhe Institute of Technology, Eggenstein-Leopoldshafen; 76021, Germany; (7) Institute of Biological and Chemical Systems, Karlsruhe Institute of Technology, Eggenstein-Leopoldshafen; 76021, Germany; (8) Department of Physics, University of Illinois at Urbana-Champaign, Urbana; IL; 61801, United StatesPublication Year:2025DOI Link:10.1002/lpor.202401697數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20250517770273 -

However, potential practical challenges such as fire hazards, and the complexity of daily cleaning are limitations in such an application. In this study, we utilized femtosecond laser direct writing technology to create femtosecond laser-induced graphene (FLIG) on flame retardant cork. The FLIG surface was then coated with multi-scale candle soot particles to incorporate carbon black (CB-FLIG) superhydrophobic surface properties. Here we demonstrate CB-FLIG as a raw material for electronic components in multifunctional wooden houses. The infrared emissivity of the CB-FLIG surface was as high as 97.2 % and the electric heating performance was good. As such, it can be used as an electric heater in the winter, and we achieved room temperature control at a comfortable 24.9 °C with 4 V voltage in a model house. Also, the water contact angle was 151.2°, giving CB-FLIG self-cleaning properties. Ultimately, we demonstrate the application of CB-FLIG in the field of smart home components such as electrical wiring, electric heaters, fire protection, and self-cleaning, increasing functionality while reducing the need for routine maintenance. This study lays a robust foundation for state-of-the-art devices within smart timber houses and significantly propels the development of versatile, interconnected wooden dwellings. ? 2024 Elsevier LtdAffiliations:(1) Hunan Key Laboratory of Nanophotonics and Devices, School of Physics, Central South University, Changsha; 410083, China; (2) State Key Laboratory of Precision Manufacturing for Extreme Service Performance, College of Mechanical and Electrical Engineering, Central South University, Changsha; 410083, China; (3) State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics of CAS, Xi'an; 710119, China; (4) Department of Desalination and Water Treatment, Zuckerberg Institute for Water Research, The Jacob Blaustein Institutes for Desert Research, Ben-Gurion University of the Negev, Sede-Boqer Campus, Midreshet Ben-Gurion, 84990, IsraelPublication Year:2025Volume:233Article Number:119853DOI Link:10.1016/j.carbon.2024.119853數(shù)據(jù)庫(kù)ID（收錄號(hào)）:20244817447614
