gate overlap

Aiming at the problem that there is no comprehensive model of coherent beam combining through superposed volume gratings, we establish a comprehensive model for two-beams combining and its analytic formula is derived using coupled wave theory.

目前基于重叠体光栅的相干组束系统还没有完整的理论模型和参数分析,针对这个问题,本文采用耦合波理论,建立了比较完整的基于重叠体光栅的双光束组束模型,给出了各光束在重叠体光栅内传播的解析解。
