However, current light detection and ranging technologies struggle to simultaneously achieve high measurement speed, accuracy, and a large non‐ambiguity range. Here, a time‐of‐flight optical ranging technique based on a repetition‐frequency‐modulated femtosecond electro‐optic comb and balanced nonlinear cross‐correlation detection is presented. In this approach, a target distance is determined as an integer multiple of the comb repetition period. By rapidly sweeping the comb repetition frequency, absolute distance measurements within 500 ns and real‐time displacement tracking at single‐pulse resolution (corresponding to a refresh rate of 172 MHz) are achieved. Furthermore, the system attains an ultimate ranging precision of 5 nm (with 0.3 s integration time). This method uniquely integrates nanometer‐scale precision, megahertz‐level refresh rates, and a theoretically unlimited ambiguity range within a single platform, while also supporting multi‐target detection. These advances pave the way for high‐speed, high‐precision ranging systems in emerging applications such as structural health monitoring, industrial manufacturing, and satellite formation flying.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"53 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084400","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}

Among photonic architectures, microring resonator (MRR)‐based optical neural networks (ONNs) are attractive due to their compact footprint and wavelength‐division multiplexing. However, MRRs are highly sensitive to environmental disturbances and crosstalk, limiting computational accuracy. While in‐situ training has emerged as an effective method to enhance system performance by adapting weights during computation, it requires real‐valued bidirectional processing to support backpropagation—a significant challenge for noncoherent MRR‐based systems. Here, an in‐situ trained MRR‐based ONN that overcomes these limitations through real‐valued bidirectional optical computing is demonstrated. By integrating multiwavelength multiplexing with on‐chip forward and backward propagation, this architecture enables physical parameter updates via optical backpropagation without lookup table dependency. Experimental validation perfectly matches digital computing results and shows a 13.3% accuracy improvement over conventional MRR weight banks in classification tasks, with sustained precision under prolonged operation. Systematic analysis confirms the architecture's robustness against thermo‐optic crosstalk and environmental variations. This work establishes a pathway toward scalable, disturbance‐resilient photonic computing for next‐generation artificial intelligence hardware.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"4 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084399","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}

Here, a general cascaded time-modulated metasurface architecture is proposed that enables on-demand tunable and reversible nonreciprocal transmission at the fundamental frequency, with time-modulation frequencies far below the incident wave frequency. By controlling the harmonics interference through different time signals applied to each layer, the metasurface enables nonreciprocal wave propagation under either forward or backward incidence. Through theoretical analysis and full-wave simulations, a reconfigurable two-layer metasurface for nonreciprocal microwave transmission is ultimately designed and verified. Experimental results confirm that the nonreciprocal strength, propagation direction, and transmission peak frequency can be dynamically tuned by controlling the time-modulation signals. The method provides an approach for designing simple yet efficient and compact real-time tunable and reversible nonreciprocal metasurface devices, holding promising potential for applications in electromagnetic wave isolation, routing, and advanced signal processing etc.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"25 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145083968","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, most ultrafast pulse shaping techniques rely on traditional 4‐f systems with multiple devices, resulting in complex configurations and limited integration and tunability. To address these challenges, here an approach for the generation of time‐varying femtosecond holographic fields based on spatial frequency multiplexed meta‐holography is proposed. This approach involves encoding various holograms into high and low spatial frequency channels of a single meta‐holographic device, thereby facilitating high‐precision control over the temporal evolution of femtosecond holographic light fields can be achieved, and demonstrating advantages of compactness, simplicity, and ease of integration. Experimentally, two examples of ultrafast holographic fields are generated, including a femtosecond vortex field with time‐varying orbital angular momentum (OAM), and a femtosecond holographic pattern varying between different letters over time. The observed temporal dynamics align closely with theoretical predictions. This work offers a new pathway for temporal modulation of ultrafast holographic fields and holds significant potential for applications in ultrafast information processing, optical communication, and integrated photonics.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"177 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084401","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}

Despite advancements in pharmacological therapies and invasive interventions, including stenting and bypass surgery, current approaches are constrained by severe side effects, risks of restenosis and perioperative complications, significant recovery burdens, and high damage to vascular tissues. There is a critical need for a minimally invasive technique capable of selectively ablating atheromatous lesions while preserving healthy vascular tissues. In this study, leveraging the unique molecular composition of atherosclerotic plaques—rich in cholesteryl esters, and substantial spectral separation between the ester and artery absorption, selective laser ablation of atheroma is demonstrated. A 5.75 µm femtosecond laser system targeting the resonance of cholesteryl ester bonds, with a high power of 1.5 W is developed based on parametric amplifiers, to assess ablation efficiency and selectivity. The atherosclerotic plaques in a murine model of atherosclerosis are fully removed within milliseconds, while no damage to the artery is observed. Furthermore, the translational potential of this technology is validated by integrating a specially designed mid-infrared anti-resonant hollow-core fiber for efficient laser energy delivery, achieving an ablation rate of 0.13 mm<sup>3</sup> s<sup>−1</sup>. These findings provide a promising strategy for rapid and selective intervention in atherosclerosis, with clear potential for clinical translation.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"58 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145083969","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}

Herein, a layer‐stacked Ruddlesden‐Popper perovskite (RPP) (PEA)2PbI4/NiPS3 (PEA and PEPI are abbreviations for phenethylamine and (PEA)2PbI4) type‐II heterojunction is proposed for the first time, which recorded an unprecedentedly fast interlayer charge transfer rate of 0.77 ps−1 (τ = 1.77 ps) with overwhelming efficiency of ≈98.4%, outperforming MoS2‐based counterparts (η ≈85%) reported till now. This efficient interfacial charge transfer and separation effectively suppresses electron–hole recombination in the PEPI/NiPS3 heterojunction, thereby extending the lifetime of photo‐generated carriers. The interlayer ≈ps scale electron and hole transfer processes are controlled by tuning the wavelengths and power of the pump laser. The efficient, fast, and controllable charge transfer process could have strong implications for the development of efficient devices based on 2D perovskite and metal thio(seleno)phosphates heterojunction instead of conventional transition metal dichalcogenides for broad optoelectronic applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"44 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077313","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}
