Abstract

This paper proposes and demonstrates a single-longitudinal-mode (SLM) actively Q-switched Yb-doped fiber laser based on compound-cavity filtering. A highly doped large-mode-area double-cladding Yb-doped fiber is employed as the gain medium. Furthermore, secondary-cavities (SCs) structure is constructed using fiber couplers, enabling the realization of SLM operation through the Vernier effect of the compound-cavity. Benefiting from enhanced intracavity energy storage, SLM laser pulses with energy exceeding 14 μJ can be obtained across the repetition rate range of 10–80 kHz, with a maximum output power of 1.1 W achieved at 80 kHz. To the best of our knowledge, this is the first demonstration of watt-level SLM Q-switched pulse output based on compound-cavity.

基于复合腔的瓦级单纵模主动调q掺镱光纤激光器

本文提出并演示了一种基于复合腔滤波的单纵模主动调q掺镱光纤激光器。采用高掺大模面积双包层掺镱光纤作为增益介质。此外，利用光纤耦合器构建二次腔（SCs）结构，利用复合腔的游标效应实现SLM操作。得益于增强的腔内能量存储，在10 ~ 80 kHz的重复频率范围内可获得能量超过14 μJ的SLM激光脉冲，在80 kHz时可获得1.1 W的最大输出功率。据我们所知，这是基于化合物腔的瓦级SLM调q脉冲输出的首次演示。

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.
