摘要
基于衍射理论和非线性小尺度自聚焦的纹波理论,推导了不同频率下的纹波经过非线性介质传输后的解析式.通过解析分析,得到了不同空间频率波前畸变的非线性增长特性.结合驱动器装置对打靶焦斑的要求,研究了波前空间频率的划分方法,并根据国内装置的特点划分了波前空间频率高中低频分界点.
Abstract
In terms of the theory of diffraction and nonlinear small-scale self-focusing,the analytical expression which described ripples of different spatial frequencies' passing through nonlinear media was induced. By analytical method,the nonlinear-gain characteristics of different spatial frequencies'wavefront distortions were obtained. The division method of the wavefront-distortion's spatial frequency was developed according to the requirements for the focal spot in drivers and the separation points between the higher,middle and lower frequencies which were assured according to the characteristics of domestic driver.
