稳定性

Along with increment of mean photon number, there is no change in the oscillation period of the squeezing curve, but its scope increases obviously and its stability begins to reduce; when the mean photon number and the field mold structure fixed, the speed of moving atom has a great infection on the extent and period of the radiation squeeze. With the speed of moving atom increasing, not only the complete squeezing effect would be archived, the stability would also enhance.

随着平均光子数的增加，压缩曲线的振荡周期没有明显的变化，压缩曲线的振荡幅度明显增大，压缩的稳定性变小；在平均光子数和场模结构参数一定时，原子运动速度对光场压缩的深度以及压缩周期影响程度较大，增大原子运动速度，不但可以实现完全压缩光场，而且压缩的稳定性得到提高。

The model for calculating the stability of the resonator containing a laser rod with curvature ends was developed,which was based on the transfer matrix theory of Gauss beam. The results from the numerical simulations on some typical resonators indicate that the laser rod with curvature ends can expand the stable region of plano-plano,plano-concave and plano-convex cavity notability;despite the laser rod with curvature ends can improve the stability of above mentioned cavities,it costs the effective mode volume.

计算结果表明，对于几类典型的谐振腔如平平腔、平凹腔，球面端面激光棒可以显著的扩展强热聚焦作用下的稳定工作范围；球面端面激光棒在提高约束稳定性和热稳定性的同时，通常是以牺牲有效模式体积为代价的。
