摘要
报道了一台主振荡功率放大(MOPA)结构的单频脉冲光纤激光器。对线宽为20 kHz、工作波长为1064 nm的连续单频激光进行强度调制,得到了平均功率为0.5 mW的单频脉冲种子激光。首先,采用三级掺Yb光纤放大器将种子激光进行预放大,获得了2.7 W的平均功率。然后,以纤芯直径和内包层直径分别为30 μm和250 μm的双包层掺Yb光纤为主放大器,在抽运光功率为87.1 W时,获得了重复频率为12 MHz、脉宽约10 ns、峰值功率为486.7 W的单频脉冲激光输出,平均功率达58.4 W。
Abstract
A master oscillator power amplifier (MOPA) structured pulsed fiber laser is reported. The single-frequency pulse seed, with the average power of 0.5 mW, is obtained by externally modulating a continuous wave laser with linewidth of 20 kHz. The pulse seed is firstly pre-amplified to about 2.7 W of average power with three Yb-doped fiber (YDF) amplifiers. The main amplifier is based on a large-mode-area (LMA) double clad YDF with core diameter of 30 μm and cladding diameter of 250 μm. When the pump power of the main amplifier is 87.1 W, a single-frequency pulsed laser with pulse duration of 10 ns and peak power of 486.7 W is generated. The average output power is 58.4 W.
