摘要
将激光器锁定于超稳定法布里珀罗(F-P)腔的腔长上，是目前获得超窄线宽激光输出的重要手段。因此，激光器的频率稳定性依靠于F-P腔腔长的稳定性。振动引起的谐振腔形变是影响超稳定光学谐振腔稳定性的主要因素。利用有限元分析的方法定量地分析了振动环境中两种实验室常用的F-P腔在不同支撑方式下的弹性形变情况。数值计算结果给出了这两种形状的超稳定F-P腔的最优化支撑方式，使其对振动引起的腔长变化达到最小化,使振动环境下的超稳腔腔长变化最小达到10-12 m。
Abstract
Locking to the laser cavity length of ultra-stable cavities is an important method to gain ultra-short line width laser output. The stability of the laser relies on the length stability of the Fabry-Perot (F-P) cavities. Vibration induced cavity deformation is one of the dominate factors that affect the stability of ultra-stable optical cavities. The elastic deformation of two general cavities with different mounting configurations in vibration environment is quantitatively analyzed. Numerical results offer the optimum mounting configurations of the two cavities, where the change of vibration-induced cavity is minimized to 10-12 m
