While femtosecond laser direct writing is a widely used processing method, the high hardness and brittleness of these materials make high-quality processing challenging. A parallel ultrafast laser direct writing method is presented via temporal focusing and the assistance of colloidal silver nanoparticles, which enables the efficient generation of high-quality debris-free nanostructures on borosilicate glass surfaces. These results demonstrate that near-field enhancement from the silver nanoparticles allows for precise material removal at substantially reduced fluences (30% of those in water), while generated bubbles in the liquid efficiently remove debris. To demonstrate the flexibility and scalability of the method, different micro- and nanoscale structures are fabricated on glass surfaces, including 1D and 2D optical gratings with different periods and a centimeter-sized grating logo. Lastly, the generality of the method on silica glass and sapphire crystal substrates is verified to show comparable resolution. This method may find important engineering applications as it provides a high-throughput, high-resolution solution for creating functional surfaces or devices (such as gratings, metasurfaces, and microfluidic channels) on different transparent materials.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"80 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130450","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 study, the lasing performance of two types of optically pumped InGaAs quantum dot microcavities – namely, micropillar and photonic-defect cavities — is systematically compared at elevated temperatures. A comprehensive analysis of device designs through simulations, followed by the fabrication and experimental studies of both structures, allows for a direct performance evaluation. Excitation-power-dependent input/output measurements confirm lasing up to 200 K in the micropillar case, where the performance is constrained by sidewall losses, pump power absorption, and inefficient heat dissipation. In contrast, the photonic-defect cavity demonstrates stable continuous-wave lasing even at room-temperature (300 K), attributed mainly to superior thermal management in the quasi-planar cavity design. Additionally, in the photonic-defect cavity with low-absorbing upper mirror, Raman spectroscopy verifies efficient optical pumping, while second-order autocorrelation measurements provide unambiguous proof of lasing at 300 K. Overall, the quasi-planar geometry of the photonic-defect cavity shows high temperature stability and supports flexible fabrication, establishing it as a promising concept for practical microlaser applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"56 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130449","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, the high defect density and numerous grain boundaries in perovskite wafers result in severe ion migration and degraded optoelectronic properties. Herein, an innovative method utilizing the synergistic effect of defect passivation and grain growth is proposed by introducing 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF₄) passivator and methylammonium thiocyanate (MASCN) vapor during the fabrication of MAPbI₃ wafers. The treated wafers demonstrate an ion activation energy (<i>E_a</i>) of 0.59 eV, a dark current drift (<i>I</i>_drift) of 8.72 × 10⁻⁵ nA cm⁻¹ s⁻¹V⁻¹, and a mobility-lifetime product (<i>µτ</i>) of 9.63 × 10⁻⁴ cm² V⁻¹, all indicative of superior performance. These characteristics enable MAPbI₃ wafer detectors to achieve an exceptional sensitivity of 30360 µC Gy_air⁻¹ cm⁻², a low detection limit (LoD) of 19.2 nGy_air s⁻¹, and a high spatial resolution of 6.38 lp mm⁻¹. Additionally, these detectors maintain outstanding operational stability after 3600 s of continuous X-ray exposure (total dose: 381.6 mGy_air) and following 45 days of storage at 60% RH.

However, high diffraction efficiency across wide angles and broad spectra is difficult to achieve with metasurfaces. As a result, hybrid meta-refractive systems face challenges in maintaining high imaging resolution over both the broadband spectrum and the wide field of view (FOV). Here, a hybrid meta-optics system (HMOS) is proposed based on an ultra-broadband aberration compensator. By integrating geometric-phase liquid crystal components (GPLCC) with polarization imaging, HMOS successfully overcomes the existing limitations of imaging systems in simultaneously achieving broadband performance, wide FOV, and high efficiency. This system demonstrates diffraction-limited imaging performance with a FOV of up to 178° and ≈100% maximum effective energy utilization theoretically across the wavelength range of 900–1700 nm. The fabricated HMOS efficiently performs polarization dehazing and polarization imaging across indoor and complex outdoor environments. Furthermore, its lightweight design enables integration with unmanned aerial vehicle platforms for remote imaging tasks in real-world scenarios. This work demonstrates remarkable potential for advancing multifunctional, high-efficiency, and easily deployable optical imaging systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"22 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130454","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}

Traditionally, high baud‐rate signal generation has been constrained by the “electronic bottleneck” of complementary metal‐oxide‐semiconductor (CMOS) digital‐to‐analog converters (DAC), making it challenging to scale up the symbol rate to 200 Gbaud and beyond. Here, for the first time, the generation of ultra‐broadband optical signals are demonstrated via spectrally‐sliced synthesis integrated on a thin‐film lithium niobate (TFLN) platform. This spectrally sliced transmitter can significantly scale up the symbol rate using existing DACs with limited bandwidth and sampling rates. The on‐chip integration in the TFLN platform not only offers a higher information density compared to bulk discrete components, but also greatly enhances the stability and performance of synthesized high baud rate optical signals through accurate phase matching. By synthesizing two spectral slices on‐chip and using DAC sampling rates of only 128 GSa s<jats:sup>−1</jats:sup>, Nyquist single‐carrier signals are generated with baud rates and line rates up to 240 Gbaud and 2 Tbit/s, respectively.

However, common implementations of US imaging require an external pulser to transmit US waves, which makes integrated PA/US imaging systems relatively complicated and suboptimal. Here, without using a US pulser, simultaneous PA and laser‐induced US (LUS) imaging is demonstrated through a semi‐transparent ultrasound transducer (sTUT). Some portion of excitation laser energy is converted to US waves when the beam passes through the sTUT, transmitting the focused US waves to targets. The other portion of light is directly delivered to the tissues to generate PA signals. This integrated bimodal approach not only eliminates the need for an electrical‐pulser but also allows the sTUT to be incorporated with a preamplifier to increase the PA signal‐to‐noise ratio. Further, the light, compact sTUT is easily integrated as part of a handheld PA/LUS system for in vivo studies of small animals and humans. Here, it photoacoustically and ultrasonically visualize not only different structures and functions of small animals but also human skin structures. The simplified handheld PA/LUS microscopic imaging system has great potential for broadband preclinical and clinical studies.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"19 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144113578","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}
