摘　　要：为了获得L波段调Q脉冲,设计了基于丙醇可饱和吸收体的调Q激光器。采用有机溶液丙醇制成液体可饱和吸收体,并测量到其调制深度为5.58%,将其应用到调Q激光器中,获得了L波段的脉冲。当激光器的泵浦功率达到230 mW时,调Q脉冲序列的输出平均功率约是0.79 mW,脉冲重复频率是20.9 kHz,单脉冲能量达36.7 nJ。In order to obtain L-band Q-switched pulse,this paper designs Q-switched laser based on Propyl alcohol saturable absorber,the saturable absorber is made of organic solution Propyl alcohol,and the modulation depth of the saturable absorber is measured to be 5.58%.The L-band pulse is obtained by applying saturable absorber to Q-switched laser.The average output power of the Q-switched fiber laser is 0.79 mW with the pulse repetition rate of 20.9 kHz and the pulse energy is up to 36.7 nJ when the pump power of the laser is 230 mW.
