- Numerical calculations are performed and show that the focal shift in focused sinh-Gaussian beams depends on the Fresnel number and decentered parameter, and increases with decreasing them. 数值计算表明，聚焦双曲正弦高斯光束的焦移与偏心参数和菲涅耳数有关，焦移随偏心参数和菲涅耳数的减小而增大。
- The results show that, when the Fresnel number is small, the low-loss mode field distribution is the low-order mode, on the contrary, the low-loss mode field distribution is the high order mode. 结果显示，模式分布类似于稳定腔的模式，并且腔的菲涅尔数越小，模式阶数越低，当菲涅尔数合适时，可实现基模振荡。
