摘要

采用级联波分复用和抽运的分段方法，极大地抑制了反射和反馈。在重复频率为50kHz、脉冲持续时间为20ns时，放大信号的增益为17.1dB，信噪比高达25dB。整个系统是大功率脉冲放大前置放大器的理想选择。

Experimental research on preamplifier for high power Yb-doped fiber pulse amplification

By using cascaded Wavelength Division Multiplexing and pumping in sectionalization method, ASE and feedback were greatly suppressed. At repetition rate of 50kHz and pulse duration of 20ns, gain of amplified signal was 17.1dB with a high signal to noise ratio of 25dB. The whole system is a good choice for a preamplifier of high-power pulse amplification.
