Abstract
Continuous-wave (CW) single-frequency fiber lasers have been widely used in optical fiber communication systems, optical fiber sensors, gravitational wave detection, laser LIDAR, nonlinear frequency conversion, and spectroscopy. In the past two decades, 1.5 μm-band single-frequency fiber lasers were greatly improved, such as laser linewidth from MHz to kHz, laser power scaling from several milliwatts level to a few hundred watts level. However, the noise suppression, linewidth as well as the output power of the single-frequency fiber laser need further research. This article reviews the key technologies of single-frequency fiber laser, and introduces the output performance and amplified characteristics of our home-made 1.5 μm-band single-frequency fiber laser, based on the DBR cavity constructed by the high-gain Er3+/Yb3+ co-doped phosphate glass fiber.
