摘要: 对大口径的薄片激光器的失调输出特性进行了理论和实验研究，V-型腔由平面输出耦合镜和凹面反射镜及孔径光阑组成。基于矩阵光学和失调衍射积分方程得到了激光器的功率失调曲线。实验测量了在200 Hz泵浦频率下加入不同孔径光阑后谐振腔失调对输出功率的影响和谐振腔失调对光束质量的影响，以及在300 Hz泵浦频率下输出功率分别与平面输出耦合镜和凹面反射镜失调的关系。实验结果表明:失调输出功率和失调角度成二次函数关系，失调容限和腔镜口径成正比，光束质量因子随失调角度的增大而变小。

Abstract: The output characteristics of misaligned resonator for large-aperture thin disk laser have been studied experimentally and theoretically. A plane output coupler S1, a concave mirror S2 and an aperture stop are arranged to define the V-shape resonator. The misalignment sensitivities of the output power are given by means of matrix optics and the misalignment diffraction integral equation. The misalignment effects of the resonator having a variable aperture stop diameter on output power and beam quality have been measured by tilt -angle measurement technique at 200 Hz pump frequency, as well as the output power relationship with the misalignments of mirror S1 and mirror S2 at 300 Hz pump frequency. The experimental results show that the output power is a quadratic function of -
