| 摘 要： | 对LD泵浦调Q双包层掺Nd3+光纤激光器进行了实验研究.在Littrow结构的体光栅与二向色镜构成的线形腔结构中,利用声光Q开关(AQM)调Q,在1064nm得到了光谱线宽约为0.08nm稳定的激光脉冲序列.脉冲重复频率从1kHz到10kHz可调.在重复频率1kHz时得到脉冲宽度约800ns,最大单脉冲能量180μJ,脉冲峰值功率225W,激光平均功率180mW,并对激光输出脉冲能量进行了计算,计算结果与实验符合很好.

| Abstract: | A laser diode pumped Q-switched Nd-doped double-clad fiber laser was studied experimentally.In linear cavity AOM is employed as the Q switching.This laser produced stable pulses with energy up to 180 μJ and a peak power of 225 W(at a repetition rate of 1 kHz).And the spectrum bandwidth of the laser was as narrow as 0.08 nm. |
