Recent experiments discovered that quantum surface effects (QSEs) of the metal, including nonlocal optical response, electron spill-out, and Landau damping, invalidate the classical electromagnetic theory and contribute additional loss sources to the SPP in the nanoscale. This hinders its applications. Going beyond the widely used classical local response approximation, we use the Feibelman d-parameter method to investigate the QSE-modified non-Markovian dynamics of quantum emitters (QEs) coupled to a SPP in a planar metal-dielectric nanostructure. A mechanism to overcome the dissipation of the QEs caused by the lossy SPP with the QSEs is discovered. We find that, as long as the QE-SPP bound states are formed, a dissipationless entanglement among the far-separated QEs is created. Compared with the local-response approximate results, the QSEs play a constructive role in establishing such a coherent correlation. The result lays a foundation for understanding the light-matter interactions in absorptive media and paves the way for the application of SPP in quantum network.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 15","pages":"31858-31874"},"PeriodicalIF":3.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144743686","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}

This study demonstrates a breakthrough by developing a volcano-shaped gold-coated holographic SBC grating optimized for the 3-4 μm range, achieving a maximum diffraction efficiency of 96.92% with an average efficiency exceeding 95% across a 1.5 μm spectral bandwidth. The self-developed 50 mm × 50 mm large-aperture grating demonstrates an excellent wavefront as low as 0.18 waves. Moreover, the engineered grating exhibited high robustness under laser irradiation exceeding 1000 W/cm2, 4 times that of the nominal commercial MIR-ruled gratings. Furthermore, this work analyzed the fundamental relationship in SBC architecture between the diffraction characteristics of MIR gratings and the linewidth properties of MIR lasers. Dual-grating SBC based on those high-performance gratings demonstrated a 92.5% combined efficiency for OPO lasers operating at 3.16 μm and 3.89 μm while maintaining nearly identical beam quality, showing 54% higher efficiency than the conventional single-ruled grating SBC scheme. The demonstrated technological breakthroughs provide transformative solutions for advanced high-power MIR laser systems.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 15","pages":"31307-31318"},"PeriodicalIF":3.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144743790","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}

Here, we report the doping profile engineering for laser ceramics via an empirical revision of Fick's diffusion model for Cr:ZnS, and its application to in-situ laser performance optimization. Using a 30% output coupler, the system achieved a maximum laser output power of 5.8 W and a maximum slope efficiency of 53.5%, reaching 81% of the intrinsic Stokes limit. The output power is further amplified to nearly 10 W with an optimized trade-off between gain and thermal management, as previously noted, which again enabled the ion concentration selection in a single-pass master oscillator power amplifier (MOPA) configuration. This approach is broadly applicable to thermally diffused gain media, paving the way for advancing high-efficiency and high-performance MIR laser sources for both fundamental research and industrial/medical applications.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 15","pages":"32890-32902"},"PeriodicalIF":3.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144743729","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}

The metasurface-based radiating patches are designed and optimized to exhibit a stable reflection phase gradient (RPG) under cross-polarized (cr-pol) incidence. For co-polarized (co-pol) incidence, extra metal strips are introduced to generate the 180° reflection phase difference in the low-frequency band for the scattering field cancellation and the uneven reflection phase distribution in the high-frequency band for scattered energy diffusion. Hence, the wideband low-scattering property can be ensured for both polarizations by appropriately arranging the aforementioned metasurface-based antenna units. A prototype of the proposed antenna array is fabricated and measured to verify the effectiveness of the proposed method. Measured results show that over 6 dB RCS reductions are achieved from 7.3-16.6 GHz and 6.7-16 GHz under co-pol and cr-pol normal incidence. Compared with reported linearly polarized antenna arrays without any additional RCS reduction structure, the proposed design realizes a significant enhancement of the RCS reduction bandwidth due to the integrated utilization of the hybrid RCS reduction mechanism.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 15","pages":"32247-32261"},"PeriodicalIF":3.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144743736","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, high-reflectivity targets often encounter to signal saturation, which introduces errors in both time-of-flight (ToF) ranging and hyperspectral reflectance calculation. Such saturation is a joint result of the spectrum of the supercontinuum laser source and the spectral response of the photodetector, and it causes an unbalanced detection performance of different spectral channels of the HSL. This paper proposed a neural network-based waveform recovery framework that addresses saturation-induced distortions in HSL systems to achieve precision ranging. What we believe to be a newly constructed fitting function was designed to simulate saturated waveforms through signal amplification, amplitude truncation, and temporal broadening. Subsequently, A dataset combining simulated and experimental data was built for training. Finally, we implemented a comparative evaluation of three neural network architectures-convolutional neural networks (CNN), radial basis function neural networks (RBFNN), and generalized regression neural networks (GRNN)-were evaluated for waveform recovery and ranging accuracy. RBFNN achieved the best balance between performance and efficiency. The results show that our method can obtain accuracy ranging for high-reflectivity targets with an average mean squared error of 60.623, an average coefficient of determination of 0.9935, and an average correlation coefficient of 0.9991. These results demonstrate that our method can solve the saturation recovery problem for HSL ranging in high-reflectivity signal acquisition.","PeriodicalId":19691,"journal":{"name":"Optics express","volume":"33 15","pages":"32155-32174"},"PeriodicalIF":3.3,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144743737","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}
