When the optical comb passes through a Mach-Zehnder interferometer, a reference frequency-shifted comb and a probe comb carrying distance information of targets are created. After filtering and heterodyne detection, two electrical signals are generated and sent to a narrowband phase detector for phase extraction, from which distance information or transfer delay can be recovered. Thanks to the broad comb spectrum, high-order comb lines exhibit high sensitivity to propagation distance and transfer the phase to the generated low-frequency electrical signals, significantly enhancing measurement precision. Experimental demonstrations show that a precision of ±10.5 fs is achieved, with a measurement range up to 50 km. Furthermore, a free-space distance measurement is performed, and a precision as small as <inline-formula> <tex-math>$2.8~mu $ </tex-math></inline-formula>m is realized. The proposed system holds great potential for widespread use in distributed network systems and 3D imaging systems.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 19","pages":"1093-1096"},"PeriodicalIF":2.3,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Up to now, the studies are limited to forward SSPs mode and the backward-wave SSPs (BWSSPs) have received little attentions in the community. In this letter, a new excitation method of BWSSPs on the uniform metal grating by using electron beam is proposed and validated by numerical simulations in Terahertz (THz) band. Due to its distinct dispersion characteristic in the first negative spatial harmonic wave region (<inline-formula> <tex-math>$n=-1$ </tex-math></inline-formula>), the propagation direction of generated BWSSPs is inverse to the electron beam. Besides, the matched momentum of BWSSPs which couples to free electron beam is larger than that of forward SSPs, thus leads to the required electron beam voltage significantly decreases. As a result, the excitation efficiency of BWSSPs by low-voltage electron beam is enhanced by double times compared to forward mode excitation according to the SSPs power spectrums. This work can provide a simple yet high-efficiency excitation method of SSPs mode working at backward regime. Moreover, it can open up new ways for the development of novel BWSSPs-based devices (e. g., sensors, couplers and radiation sources, etc.) in THz and/or microwave band.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 19","pages":"1089-1092"},"PeriodicalIF":2.3,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144556575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although cylindrical vector pulses with several tens of megahertz repetition rate can be obtained directly at the laser source with high-purity structured modes, cylindrical vector pulses with hundreds of megahertz or gigahertz repetition rate have greater application prospects in the fields of laser processing and super-resolution imaging. Here, we report on the generation of a repetition-rate of 435.8 MHz, cylindrical vector pulses from a fundamentally mode-locked Yb-doped solid-state fiber laser. The nonlinear-polarization-evolution (NPE) mode-locking and high pump power injection enabled short pulses with high repetition rate, while on-demanded cylindrical vector beams including radially and azimuthally polarized beams were yielded by adjusting the polarization control elements inside the cavity. Mode-locked pulses were delivered with an average power of 315 mW, a spectrum bandwidth of 23 nm, and a pulse duration of 904 fs. To the best of our knowledge, it is the highest repetition rate from a fundamentally mode-locked Yb-fiber laser which directly generates cylindrical vector pulses.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 20","pages":"1145-1148"},"PeriodicalIF":2.3,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Gerchberg-Saxton (GS) algorithm and the hybrid input-output (HIO) algorithm are widely used for beam shaping; however, they exhibit notable limitations. While the GS algorithm converges quickly, it is prone to stagnation at local minima. Conversely, the HIO algorithm improves exploration but suffers from instability due to fixed parameter settings. This study proposes an improved phase retrieval algorithm that integrates the strengths of both GS and HIO. It introduces an adaptive damping factor (<inline-formula> <tex-math>$alpha $ </tex-math></inline-formula>) that increases over iterations to enhance uniformity while maintaining stability. Additionally, a dynamic interpolation strategy is applied to the <inline-formula> <tex-math>$beta $ </tex-math></inline-formula> parameter to prevent divergence. Numerical simulations confirm the superior performance of the proposed method, achieving a beam uniformity of 88.62% and an energy efficiency of 72.63%, outperforming both the GS and HIO algorithms. This method effectively balances convergence speed, stability, and uniformity, offering a promising solution for high-precision beam shaping. In the experimental validation, the generated grayscale hologram is uploaded to the liquid crystal spatial light modulator (LCSLM), thereby facilitating the homogenization of the vertical-cavity surface-emitting laser (VCSEL) beam. This process yields a rectangular flat-top beam with a measured beam uniformity of 83.85%.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 19","pages":"1097-1100"},"PeriodicalIF":2.3,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144556574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
