理论分析并数值模拟了腔内光强随角锥棱镜旋转的变化,实验证明在角锥棱镜腔Nd: YAG／Cr4+:YAG被动锁模激光器中,偏振耦合输出得到了锁模深度和锁模几率近乎100％的线偏振被动锁模脉冲输出。通过旋转角锥棱镜改变偏振耦合输出、调节腔内光强,可以得到被动锁模和被动调Q两种状态的脉冲输出,脉冲能量166．5 mJ／pulse,脉冲动静比高达59．7％。
Theoretical analysis and numerical simulation of the cavity with the light intensity with the rotation of the cube corner of the change, the experiment shows that in the pyramid prism cavity Nd: YAG / Cr4 +: YAG passive mode-locked laser, polarization coupled output obtained mode-locking depth and clamping probability Nearly 100% linearly polarized pulse mode-locked pulse output. By changing the polarization coupling output by rotating the pyramid prism and adjusting the light intensity in the cavity, the pulse output of 166.5 mJ / pulse with pulse mode energy of 59.7% can be obtained.
