【摘要】 报道了角锥棱镜腔Nd3+:YAG激光器的被动锁模理论分析和实验研究．理论分析并数值模拟了角锥棱镜旋转导致的腔内偏振态和光强的变化。利用偏振镜得到了线偏振的脉冲激光输出,并且和角锥棱镜一起改变腔内偏振态。实验中通过旋转角锥棱镜改变腔内的偏振态,调节腔内光强,得到被动锁模和被动调Q两种状态的脉冲输出,与理论分析的结果相一致。更多还原

【Abstract】 Theoretical and experimental study of passively mode-locked Nd3+:YAG laser is reported. Light intensity in cavity that changes with the rotation of corner cube is analyzed and the numerical simulation results are provided. By using polarization, pulse output of linear polarization state is obtained. By rotating the corner cube to vary the polarization and the intensity in cavity, we can change the pulse state from passive mode-locking to Q-switching. It is in agreement with theoretical analysis.更多还原
