在Ce：KNSBN晶体中双光束耦合的光束整形

本文的工作是利用在光折变晶体Ｃｅ：ＫＮＳＢＮ中，其光生载流子的迁移机制在空间电荷场形成过程中是以扩散为主的特性，使得能量从变形的泵浦光转移到信号光上去，而无相位转移，从而实现泵浦光的整形。

Wave beam cleanup in the crystal Ce:KNSBN using two wave mixing

This paper includes that for the crystal Ce: KNSBN in which photocarrier diffusion dominates over drift in the formation of the space charge field, energytrnsfers from severely aberrated intense pump beam to a weak single beam without phase cross talk and we can realize pump beam cleanup using two wave mixing.
