摘　　要：分析Cr^(4+):YAG被动锁模机理及KTP晶体的倍频效率,设计合适的谐振腔以保证Cr^(4+):YAG处有足够大的激光功率密度和通过KTP的光束为平行光束。实现了Cr^(4+):YAG作为可饱和吸收体的脉冲式Nd:YAG内腔倍频激光器的被动锁模运转,得到波长532nm、输出能量为13.5mJ的皮秒单脉冲序列。This paper analyzes the mechanism of Cr4+ :YAG passive mode-locking and frequency doubled efficiency of KTP crystal. A suitable cavity has been designed to ensure the largest laser power density in Cr4 + : YAG and the parallel beam of light through the KTP crystal. By using Cr4+ :YAG as a saturable absorber, we have realized the passive mode-locking operation of a pulsed intracavity frequency doubled Nd:YAG laser and obtained the single pulse train with the output energy of 13. 5mJ at 532nm and with picoseconds pulse duration.
