摘要/Abstract

摘要： 研制了一种具有频率调谐功能的 2 µm 波段分布 Bragg 反射 (DBR) 型单纵模光纤激光器。该激光器基于石英玻璃单模掺铥光纤和 793 nm 半导体激光器泵浦源, 其光电器件分离集成在 1U 机箱内。通过内置压电陶瓷 (PZT), 可实现对激光频率的快速调谐，调谐范围约 6 GHz; 通过 TEC 温度控制, 可实现对激光频率在 29 GHz 范围内无跳模调谐。单纵模激光输出功率为 18.2 mW, 输出激光信噪比大于 60 dB, 泵浦转换效率达 27%。该激光器样机可望在高分辨光谱、量子信息以及非线性频率变换等领域发挥重要作用。

Abstract: A 2 µm distributed Bragg reﬂection (DBR) single-longitudinal-mode ﬁber laser with frequency tuning function is presented. The laser is based on single-mode thulium-doped silica glass ﬁber and pumped by 793 nm semiconductor laser pump source, and its optoelectric devices are integrated into a 1U chassis in a separate state. Fast frequency tuning of the laser can be realized through a built-in piezoelectric transducer (PZT), and the tuning range is about 6 GHz. The laser frequency can also be tuned without mode hopping in the range of 29 GHz through TEC temperature control. The output power of the single-longitudinal-mode laser is 18.2 mW, the signal-to-noise ratio is greater than 60 dB, and the pump conversion eﬃciency is 27%. This laser prototype is expected to play an important role in the ﬁelds of high-resolution spectroscopy, quantum information and nonlinear frequency transformation.
