摘要
在考虑光场的近轴衍射、走离效应和晶体吸收等因素的情况下,采用逐次逼近迭代法,对任意空间分布的高功率激光通过Ⅰ类匹配的KDP晶体倍频的逆问题〔1〕,即给定倍频光和KDP倍频晶体参数,求基频光的空间分布,作了详细研究,并给出了相应的数值计算结果。
Considering the effects of diffraction,walk-off and absorbability and using successive iteration computing method,the inverse problem of high-power second harmonic system,namely,to find the input fundamental field profile from the given output second harmonic field and KDP parameters has been studied in detail.Illustrative numerical results for KDP second harmonic system have been given.
