理想自聚焦和自散焦光限幅的分析

Analysis of Perfect Self-Focusing and Self-Defocusing of Power Limiting

分析产生非线性相移的光束在一个附加线性透镜焦平面区域的强度分布图，研究非线性自聚焦和自散焦的机制，以期获得理想自聚焦、自散焦光限幅的能力。

This paper explores intensity distribution of a nonlinearity phase shifted beam within the vicinity of the focal plane of an additional lens,studies the nonlinear self focusing and selfdefocusing mechanisms.We hope to get better capability of a self focusing or self defocusing power limiting device.
