INVESTIGATION ON LINEWIOTH OF A CPM Nd:YAG LASER
【摘要】 本文报道了同时采用Fabry-Perot标准具和光栅监测对撞脉冲锁模Nd:YAG激光器输出线宽的初步结果,通过改变泵浦能量获得0.11nm~0.25nm的激光线宽,表明了自相关调制在锁模激光脉冲线宽展宽中起着重要的作用;并对一些相关实验进行了观测。
【Abstract】 In this paper we report our initial results on the measuremet of laser linewidth using a Fabry-Perot etalon and grating simultaneously for a CPM Nd:YAG laserLaser linewidth 0.11nm~0.25nm is obtained by means of changing pump energy Experiment had indicated that the self-phase modulation plays an important role in the linewidth broadening of mode-locked pulses.Some experiments relative to the linewidth are observed.
