摘要
使用透射式半导体可饱和吸收镜(SESAM),实现了光纤耦合半导体激光抽运Nd∶YAG晶体的连续波锁模运转。根据ABCD矩阵传输理论,对激光器谐振腔的像散、稳定性与腔参数的关系进行了理论计算。在此基础上,设计了Z型折叠激光谐振腔,获得了稳定的1064 nm皮秒锁模激光输出。当抽运功率为7.7 W时,最大输出功率为372 mW。重复频率为54 MHz。经测量此时锁模脉冲宽度为8.9 ps。
A passively mode-locked Nd∶YAG laser with a partially reflective semiconductor saturable-absorber mirror is reported.According to the well known ABCD matrix theory,the astigmatism and the stability in the cavity of the laser are theoretically analyzed.Stable continuous-wave mode locked pulses are achieved with a Z-type resonator.The average output power of 372 mW is obtained with the incident pump power of 7.7 W.The pulse duration is measured to be 8.9 ps with a repetition rate of 54 MHz at the central wavelength of 1064 nm.
