摘要
利用Cr^(4+):YAG和声光锁模器联合对光纤耦合LD抽运Nd:YAG激光器进行主被动锁模,比较和分析了Cr^(4+):YAG被动锁模,声光锁模器主动锁模及两者联合主被动锁模三种情况下平均输出功率的特性,结果表明主被动联合锁模克服了主动锁模稳定性差、被动锁模输出功率低、锁模不完全的缺点,得到幅值和能量抖动小于±6%、锁模深度100%、脉宽小于410ps、输出平均功率290mW的绿光锁模脉冲。
Using Cr4＋：YAG and acousto-optic mode-locker jointly, the fiber coupling LD pumping Nd： YAG laser was actively-passively mode-locked. The output average power of passively mode-locked by Cr4＋：YAG only, actively mode-locked by acousto-optic mode-locker only and mode-locked by Cr4＋：YAG and acousto- optic jointly axe compared and analyzed. The result shows good resolution to the low output energy and stability, and the mode-lock amplitude and energy fluctuation is less than ±6%, with the depth of mode locking of 100%, pulse width less than 410 ps and output average power near 290 mW.
