高功率脉冲双包层光纤激光器的新进展

对高功率脉冲双包层光纤激光器的国内外研究进展进行评述，通过建立了小信号瞬态增益模型，对脉冲激光信号经过双包层光纤放大后的波形进行了数值模拟。分析了基于MOPA方式脉冲双包层光纤激光器的几个问题，报道了中科院上海光机所采用振荡-放大（MOPA）方法获得133．8W平均功率脉冲放大输出的实验结果。

The recent progress of the high power pulse double cladding fiber lasers are reviewed, the simulation calculation for pulse sharp amplified by the double cladding fiber is obtained by using small signal instantaneous gain model. The key points of the master-oscillator fiber power amplifier (MOPA) are analysied in detail. The system can emits average power up to 133.8 W at the wavelength of 1064 nm and repetition rate of 100 kHz.
