使用光子晶体光纤棒作为增益介质,设计了皮秒脉冲放大器的实验光路。通过实验研究分析了光子晶体光纤棒皮秒脉冲放大器的输出功率、斜率效率与光光转换效率、光束质量、重复频率、脉宽、光谱。获得了最大平均功率为101.7W,重复频率为30MHz,脉宽为6.4ps,横向和纵向光束质量分别为1.111,1.017的近衍射极限输出,放大器的斜率效率达到了65%,光光转换效率达到了58.9%。
We used the rod-type photonic crystal fiber as a gain medium and designed an experimental system for picosecondpulse amplifier. Output power, slope efficiency and optical-to-optical conversion efficiency, beam quality, repetition rate, pulse width, spectrum of the rod-type photonic crystal fiber picosecond amplifier were analyzed. As a result,we got a maximum average power of 101.7 W,repetition rate of 30 MHz,pulse width of 6. 4 ps,beam quality of Mx^2= 1. 111,My^2 = 1.017 near diffraction limit laser with slope efficiency of 65% and optical-to-optical conversion efficiency of 58. 9%.
