Among existing techniques, compressed optical-streaking ultra-high-speed photography (COSUP) uses a coded aperture and a galvanometer scanner to capture non-repeatable time-evolving events at the 1.5 million-frame-per-second level. However, the use of a randomly coded aperture complicates the reconstruction process and introduces artifacts in the recovered videos. In contrast, non-multiplexing coded apertures simplify the reconstruction algorithm, allowing the recovery of longer videos from a snapshot. In this work, we design a non-multiplexing coded aperture for COSUP by exploiting the properties of congruent sphere packing (SP), which enables uniform space-time sampling given by the synergy between the galvanometer linear scanning and the optimal SP encoding patterns. We also develop an implicit neural representation-which can be self-trained from a single measurement-to not only largely reduce the training time and eliminate the need for training datasets but also reconstruct far more ultra-high-speed frames from a single measurement. The advantages of this proposed encoding and reconstruction scheme are verified by simulations and experimental results in a COSUP system.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"24027-24038"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A parameterization model of the mixed-layer turbulence structure was developed, with a particular focus on the impact of vertical resolution on the estimation of the atmospheric refractive index structure constant (Cn2). By comparing models constructed at 10 m, 50 m, and 100 m resolutions, the robustness of the exponential decay model was validated. The results reveal significant regional differences in turbulence attenuation: Sites A and C exhibit a classical h-4/3 decay pattern, while Site B shows an h-2 behavior, likely related to local atmospheric stability and terrain conditions. To address the presence of localized strong turbulence thin layers within the entrainment zone, a dual-model framework was proposed, integrating a lognormal statistical model with a temperature gradient-based polynomial method. This approach enables quantitative assessment of anomalous Cn2 enhancements. The framework demonstrated good performance in characterizing optical turbulence in the entrainment zone across all three sites, providing preliminary evidence of its applicability. Furthermore, it offers reliable data support for the design of adaptive optics in astronomical observations, the optimization of laser communication stability, and atmospheric pollutant dispersion modeling.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"23534-23554"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With an inline optical setup for three-color pulse generation and relative phase control, we observed that the THz pulse energy can be enhanced up to 6 times compared with the conventional two-color excitation scheme, dependent on the incident fundamental pulse energy. The polarization of the enhanced THz pulse was found to be elliptical, with the second and third harmonics components of the three-color pump also being elliptically polarized. With the 3.9 µm driving pulses, the maximum THz pulse energy reaches 39.4 µJ with a conversion efficiency of about 1%. Based on the plasma current model, we analytically and numerically reproduced the THz energy enhancement, as well as its dependence on incident pulse energy. The THz enhancement can be attributed to the two additional ionization wave mixing channels introduced with the addition of the third harmonic.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"22610-22631"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, volume holographic gratings (VHGs), while suitable for NEDs, suffer from high angular selectivity, limiting the FOV for monochromatic light and causing color dispersion when illuminated by a broadband light source, leading to color variations across the displayed image. To address this issue, we report a method to simultaneously enhance the FOV and improve color uniformity by designing Bragg-matched, reflection-type, angular multiplexed VHGs. This approach ensures consistent diffraction properties for different angles of incidence, producing uniform color across the entire FOV. Numerical simulations demonstrate a reduction in spectral bandwidth from 42.7 nm to 14.7 nm throughout a 24o FOV, by using 3 times multiplexed holographic couplers. The experimentally measured FOV is approximately 25.3°. Further measurements performed using a spectroradiometer show that the multiplexed waveguide system exhibits improved color uniformity across the FOV compared to the conventional waveguide with red and blue contributions reduced from 47.8% to 0% and 20.6% to 8.5%, respectively. The optical simulations and experimental validation show a significant improvement in color uniformity compared to conventional methods, making it highly suitable for applications requiring precise and consistent color output.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 11","pages":"22255-22269"},"PeriodicalIF":3.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144294553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
