Abstract

The problem of propagation of a light beam with speckle in a photorefractive crystal with diffusive photoresponse is solved analytically. While the angular spectrum of the beam remains Gaussian, the beam is deflected, with a rate of rotation proportional to the square of the divergence angle.

非线性光学现象与器件:光折变晶体中光束路径的自偏转
用解析方法解决了带散斑的光束在具有扩散光响应的光折变晶体中的传播问题。虽然光束的角谱仍然是高斯的,但光束被偏转,其旋转速率与发散角的平方成正比。
