光纤激光器窄线宽全光纤主振荡功率放大 fiber laser narrow linewidth all-fiber format master oscillator power amplifier

摘要

搭建了一台全光纤结构的窄线宽高功率掺镱光纤激光器。种子激光的输出功率大于40 mW，线宽窄于100 MHz。采用主振荡功率放大结构三级放大，主放泵浦功率为405 W时得到了334 W的窄线宽高功率激光输出，光光转换效率为82.4%。目前，激光器输出功率仅受限于泵浦功率，增加有效泵浦功率即有望进一步提高输出功率。

Abstract

A narrow-linewidth high power Yb-doped fiber laser in all-fiber format is set up. The seed laser has an output power of more than 40 mW with linewidth narrower than 100 MHz. The fiber laser employs three-stage master oscillator power amplifier(MOPA) configuration. It outputs 334 W narrow-linewidth laser when pumped with a total power of 405 W in the main amplifier. The optical-to-optical conversion efficiency is 82.4%. Presently, the output power is limited by the pump power. It can be predicted that the laser power can be further scaled with increased available pump power.
