Abstract

In this paper, we present a single-longitudinal mode (SLM) Ytterbium-doped fiber laser (YDFL) featuring a six-subring cavity (SSRC) structure. The YDFL achieves SLM output through use of the SSRC architecture. We evaluated the stability of both wavelength and power during the experimental measurements. The results show that the wavelength and power fluctuations over one hour were less than 0.01 nm and 0.03 dB, respectively. Measurements confirmed that the YDFL, with the SSRC structure, operates stably in a SLM state. Finally, by applying Lorentzian fitting to the measured data, a linewidth of 2.4 kHz was obtained.

使用四个 2 × 2 光纤耦合器的多子环环腔单纵模掺镱光纤激光器

本文提出了一种具有六亚腔结构的单纵模掺镱光纤激光器（YDFL）。YDFL通过使用SSRC体系结构实现SLM输出。在实验测量中，我们评估了波长和功率的稳定性。结果表明，1 h内波长波动小于0.01 nm，功率波动小于0.03 dB。测量结果证实，具有SSRC结构的YDFL在SLM状态下稳定运行。最后，对实测数据进行洛伦兹拟合，得到了2.4 kHz的线宽。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
