连续单频光纤激光器在光纤通信、光纤传感、引力波探测、激光雷达、非线性频率转换、光谱学等领域有着广泛的应用前景,发展十分迅速.近20年来,1.5 m波段连续单频光纤激光性能不断提高,如激光线宽从兆赫兹到千赫兹、功率从毫瓦到近百瓦量级,但激光器的噪声抑制、放大线宽展宽、输出功率等仍有待进一步研究.本文回顾了获得1.5μm波段连续单频激光输出的关键技术,总结了本课题组基于磷酸盐玻璃光纤短腔Bragg反射(DBR)结构实现1.5 m波段连续单频光纤激光性能,以及单频激光功率放大的研究进展.
Continuous single-frequency fiber lasers have been widely used in the fields of optical fiber communication, optical fiber sensing, gravitational wave detection, laser radar, nonlinear frequency conversion, spectroscopy and other fields and have developed rapidly.In the past 20 years, the continuous single- The laser performance continues to improve, such as the laser linewidth from megahertz to kilohertz, power from milliwatts to nearly a hundred watts, but the laser noise suppression, amplification linewidth broadening, output power, etc. remains to be further studied.This article reviews the 1.5μm band of continuous single-frequency laser output of the key technologies, summarized our group based on the short glass fiber Bragg reflection (DBR) structure to achieve 1.5 m band continuous single-frequency fiber laser performance, and single-frequency laser power amplification research progress .
