| 摘 要： | 以Shooting法为基础,研究了吸收、增益和晶体厚度对光折变晶体中逆向二波混合的影响,对近似计算所引起的误差进行了讨论。对晶体表面内反射对光束透过率的影响,提出了以Shooting法为基础的自洽计算方法,计算了透过率与晶体表面反射率的关系。

| Abstract: | The effects of absorption, gain and the thickness of crystals on the antiparallel two wave mixing in photorefractive crystals have been studied based on Shooting method. The error led by approximate calculation has been estimated. A self-consistent calculation based on Shooting method has been developed to consider the effects of the reflection on the interior surfaces of crystals on transmission. The dependence of transmission factor on the reflectivity of crystal surfaces has been calculated. |
