摘要: 研制了一台全光纤结构主振荡功率放大型掺镱单频光纤激光器。该光纤激光器包括种子激光器和级联放大器两部分。种子激光器是自行搭建的环形腔结构的单频窄线宽光纤激光器。在976 nm半导体激光器泵浦下,能够输出线宽为10 MHz量级、波长为1 079.88 nm的单频光,激光功率为10.02 W,光-光转化效率为58.9%,斜率效率为65.3%。Abstract: An all-fiber master oscillator power amplifier(MOPA) structured single-frequency fiber laser is demonstrated. The seed laser is a self-designed ring cavity structure which outputs a single-frequency laser beam. The 10 MHz linewidth, 1 079.88 nm MOPA laser has a output power of 10.02 W, when pumped by a diode laser at 976 nm. The signal-to-noise is about 30 dB, the slope efficiency is 65.3% and the optical-optical conversion efficiency is 58.9%.
