Metasurfaces, with their subwavelength-scale structures, offer flexible control ability, enabling them to be an ideal platform for single-pixel imaging applications. This study introduces an innovative single-pixel imaging technique that leverages polarization multiplexing metasurfaces to enable dual orthogonal polarization channel imaging from a single measurement. By incorporating four units with varying structural dimensions, 2-bit encoding of the incident light is achieved. Through spatial shifting, images corresponding to different polarization channels with various spatial amplitude masks are encoded independently, resulting in high-quality single-pixel imaging. This multifunctional metasurface streamlines conventional polarization-based single-pixel systems, reducing both time and spatial costs with a single measurement, while achieving a spatial resolution of 4.38 µm in reconstructed images. This innovative approach to polarimetric single-pixel imaging holds great potential for optical detection, target recognition, aviation, and other advanced applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"55 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145083964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, weak Raman signals from gas‐phase species pose significant challenges to detection sensitivity, even with high‐power laser sources. Here, cavity‐enhanced stimulated Raman photoacoustic spectroscopy is reported using continuous‐wave mW‐level near‐infrared lasers, achieving remarkable sensitivity and resolution. This approach involves coupling the pump and Stokes beams into a high‐finesse (>220 000) Fabry‐Perot cavity, enhancing the intracavity power of both lasers by four orders of magnitude. By modulating the light intensity of the pump laser, the stimulated Raman scattering‐induced acoustic waves are sensitively detected by a microphone. Additionally, a difference frequency scanning method is introduced that resolves narrow‐linewidth Raman transitions by tuning the length of the dual‐laser‐locked optical cavity. The effectiveness of the method is validated by measuring the Raman rotational transition S0(0) of hydrogen, achieving a minimum detection limit of 0.5 ppm with a 200‐s averaging time.

Realizing these applications requires UV ML materials with reliable, self‐recoverable emission. Here, self‐recoverable ML is reported from undoped magnesium fluoride (MgF2), with emission from UV to the visible blue range. This ML originates from fluorine vacancies induced by oxygen incorporation during solid‐state sintering and the crystal field of the sintered MgF2. Density functional theory calculations reveal that these vacancies create intermediate energy levels that facilitate ML emission. Notably, X‐ray irradiation enhances ML intensity by nearly threefold, owing to the increased population of charge carriers trapped at defect states. The mechanism underlying the self‐recoverable UV ML emission is elucidated through an analysis of the piezoelectric properties and trap‐level distribution of MgF2. Leveraging its high transparency and invisibility under UV illumination, a stealth anti‐counterfeiting device retrievable only by mechanical stimulation—overcoming the vulnerability of conventional ML‐based systems to unauthorized retrieval is demonstrated.

Nonlinear wavelength conversion in integrated photonic chips offers a promising approach to creating compact tunable MIR sources, serving as a competitive alternative to quantum cascade lasers, interband cascade lasers, and optical parametric oscillators. Here, ultra‐broadband MIR wavelength conversion in germanium‐on‐silicon (Ge‐on‐Si) waveguides is achieved for the first time using a continuous‐wave pump source. A maximum conversion efficiency of −27.71 dB is attained with a moderate pump power of 22.14 dBm.

Here, a high-pressure processing strategy is demonstrated to significantly improve the photoluminescent efficiency of the 0D OIHP [3-FPEA]6(Sb2Cl10)*2Cl. Notably, [3-FPEA]6(Sb2Cl10)*2Cl with blue emission at ambient conditions achieved a white-light emission after pressure treatment of 30.0 GPa. The white-light emission is mainly the result of the cooperative emission of the singlet state emission of organic molecules and the self-trapped excitons (STEs) emission related to inorganic octahedra. This irreversible emission transformation correlates with pressure-induced permanent structural amorphization and the pronounced steric hindrance imparted by the conformationally bulky 3-FPEA cations. Moreover, a marked piezochromism from blue emission to yellow emission in compressed [3-FPEA]6(Sb2Cl10)*2Cl is observed, which is associated with the energy transfer from organic components to inorganic components under pressure. Furthermore, the distortion of the inorganic octahedron and the weakening of hydrogen bond vibrations are the key factors contributing to the enhancement of the yellow light. This study provides a new perspective on the modulation of coordinated emission originated from organic and inorganic components in OIHPs materials and a new platform for the development of high-quality single-component white-light-emitting materials.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"72 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145083965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Most SPI systems are constrained by a scanning paradigm to acquire the 1D signal, which limits the imaging frame rate to the modulation speed of spatial light modulators or tunable light sources. To address the challenge of low imaging rates, a scan‐less speckle encoded SPI (SSE‐SPI) approach is proposed that leverages the advantages of speckle encoding and dual optical frequency combs (DOFCs). The spatial speckle encoding mask, generated from a disordered structure, facilitates high compression rates, enabling rapid imaging. Additionally, DOFCs can deploy spatial speckle encoding masks in parallel, thereby overcoming the limitations associated with the serial scanning process. By eliminating the scanning mechanism, an offline imaging frame rate of up to 20 MHz and a substantial spatial‐temporal information flux of 15.68 giga‐pixels per second are demonstrated through the application of an artificial neural network for image reconstruction.
