Abstract

This paper presents a single longitudinal mode fiber laser with a wide mode-hop-free tuning range. By adopting a distributed Bragg reflector (DBR) structure and optimizing the cavity length and packaging stress, a mode-hop-free tuning range of 1.37 nm is achieved. To the best of our knowledge, this is the largest mode-hop-free tuning range reported for DBR single longitudinal mode fiber lasers. The relative intensity noise (RIN) of the laser was suppressed to near the shot noise limit through a semiconductor optical amplifier, with power fluctuations confined to 0.18 % over 2 h. This low-noise, widely tunable 1053 nm DBR laser demonstrates significant potential for applications in precision spectroscopy and related fields.

低噪声1053 nm DBR单纵模光纤激光器，具有1.3 nm无跳模调谐范围

本文提出了一种具有宽无跳模调谐范围的单纵模光纤激光器。通过采用分布式布拉格反射器（DBR）结构，优化腔长和封装应力，实现了1.37 nm的无跳模调谐范围。据我们所知，这是DBR单纵模光纤激光器中最大的无模跳调谐范围。通过半导体光放大器将激光器的相对强度噪声（RIN）抑制到接近射散噪声的极限，在2 h内功率波动限制在0.18%以内。这种低噪声、宽可调谐的1053 nm DBR激光器在精密光谱及相关领域具有重要的应用潜力。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
