It is highly demanded to achieve customized high-fidelity spatiotemporal field manipulation with a single ultrafast pulse. Here, we propose a checkerboard modulation scheme, with the simple setup of a cylindrical-lens-grating-lens configuration, successfully shaping a single ultrafast pulse into customized spatiotemporal images. We experimentally demonstrate spatiotemporal images, such as panda, QR code, and Zhejiang University eagle logo, in the spatial and temporal dimensions. By manipulating both the amplitude and phase of the pulse, we achieve spatiotemporal vortex arrays with different orbital angular momenta at various spatiotemporal positions, with spatiotemporal-mode division multiplexing potential for optical communications.

However, the absence of high-speed spatial light modulators (SLMs) poses a challenge in the pursuit of high-speed, real-time MMF imaging. Silicon optical phased array (OPA) serves as a possible solution to high-speed mode field manipulation; however, the nonlinearity in the phase response of silicon p-i-n diodes makes it unfeasible to realize precise multilevel control at a high speed. In this paper, it is shown that the driving scheme of p-i-n diodes in a silicon OPA can be simplified by using binary modulation, enabling the use of high-speed digital voltage drivers instead of high-precision digital-to-analog converters. The OPA achieves modulation at 1 MHz, which is three times faster than state-of-the-art SLMs. Experimental results demonstrate a frame rate of up to 500 frames per second. The image-reconstruction period is as short as 0.1 ms per frame, making the system suitable for real-time imaging. The measured spatial resolution is 2.3 µm with a field of view diameter of 105 µm, which approaches the diffraction limit.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"16 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672617","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}

Excited by 254 nm, Pt⁴⁺-doped Cs₂ZrCl₆ compounds can exhibit the characteristic emissions of host and Pt⁴⁺, resulting in the polychromatic luminescence caused by the efficient energy transfer from host to Pt⁴⁺. Through combining the theoretical calculation and luminescence profiles, it is clear that the broadband emission at 660 nm is assigned to the self-trapped exciton of [PtCl₆]²⁻ octahedron. Furthermore, compared with that of Er³⁺-doped sample, the intensity of the NIR-II emission of Er³⁺ at 1540 nm in Pt⁴⁺/Er³⁺-codoped Cs₂ZrCl₆ double perovskite phosphors is greatly improved, namely, a 127-fold increase, due to efficient energy transfer from host and Pt⁴⁺ to Er³⁺. Furthermore, the quantum efficiencies of the visible and NIR-II emissions in Cs₂ZrCl₆:0.6%Pt⁴⁺/25%Er³⁺ double perovskite phosphor are 75.5% and 34%, respectively, excited by 254 nm. Additionally, via utilizing the designed phosphors, various applications including multilevel anti-counterfeiting, non-visual imaging, night vision, etc., are realized. This finding implies that NIR-II emission of Er³⁺ in double perovskite phosphors can be efficiently regulated via using multi-channel composite energy transfer engineering.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"95 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675392","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, in contrast to the widely-observed enhanced circular dichroism (CD), moderate/narrow-band optical activity (OA) responses are usually seen in chiral metadevices. Here, by engineering the chirality parameter that determines the effective refractive indices associated with the two CP eigenstates, a three-dimensional (3D) metamaterial consisting of 3D-printed ceramic meta-atoms exhibiting broadband strong OA with nondispersive near-zero ellipticity in the millimeter-wave regime is demonstrated. With four-fold rotational symmetry (<i>C</i>₄), the 3D dielectric metamaterial shows near-identical co-polarized transmission magnitude but distinct phase retardations under left-handed circularly polarized (LCP) and right-handed circularly polarized (RCP) illumination over a broad frequency range. Field analysis indicates that the observed OA behavior originates from the handedness-dependent light-matter interaction between the chiral meta-atoms and CP waves. Furthermore, large transmission CD and CP polarization conversion are observed in a metamaterial with <i>C</i>₂-symmetry, demonstrating the proposed systems’ versatility in CP wave control. As revealed by the present study, coherently exploring the complex parametric space offered by 3D meta-atoms based on state-of-the-art 3D fabrication techniques can become a promising paradigm for engineering metamaterials with sophisticated functionalities.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"23 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675391","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}

Employing multi-contrast PAM expands the potential for non-destructive and label-free analysis of various substances. The efficiency of multi-contrast PAM largely depends on laser sources possessing high pulse switching rates. Recently, a dual-wavelength switchable fiber amplifier operating in the near-infrared-II (NIR) window is reported for multi-contrast PAM. Nevertheless, transitioning to the NIR-III region, which has higher absorption peaks, presents challenges due to the fixed Raman frequency shift and the absence of suitable pumps, complicating the search for a switchable source within this window. Herein, a unique dual-wavelength switchable all-fiber laser functioning within the NIR-III region is presented via a hybrid optical amplifier. Thanks to flexible optical parametric conversion, the laser produces 1.5 µJ pulses and realizes arbitrary pulse trains with 1725-nm and 1930-nm wavelengths. Simultaneously, utilizing programmable pulse shaping for two telecom lasers, the proposed source generates high power-spectral-density pulses with a flexible pulse width and a switching frequency of up to 100 kHz. Multi-contrast PAM using the proposed source distinguishes between the two types of microplastics in water, presenting a promising methodology for efficient microplastic detection in aqueous environments.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"10 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666453","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}

In this work, comprehensive radiation tests under simulated space conditions on InAs/GaAs QDs and lasers is conducted to validate their performance. The results reveal that InAs/GaAs QDs with filling factors exceeding 50% exhibit enhanced radiation hardness.

Nevertheless, current multi-spectral camouflage strategies face challenges, including inadequate performance compatibility across bands, insufficient comprehensive camouflage bands, and limited applicability to diverse scenarios. A novel functional multispectral camouflage strategy with practical application potential is proposed here. This strategy integrates infrared and microwave camouflage metamaterials into a flexible transparent structure, achieving multispectral camouflage across infrared, microwave, and laser detection bands while maintaining flexibility and optical transparency. This strategy features a simple fabrication process and is compatible with mature micro-nano fabrication techniques, enabling large-scale production of the samples. In a proof-of-concept demonstration, a sample with an area of 18 × 18 cm² is fabricated based on micro-nano processing technology. Experimental results show that the design achieves: high visible transmittance (&gt;60%), low emissivity (0.36/0.35) in the atmospheric window, high emissivity (0.62) in non-atmospheric window, low reflectance (&lt;0.2) at 1.55 µm, high absorptivity (&gt;0.9) in 4.4–18 GHz.
