摘要：

介绍了波导DCN激光器的原理和结构,重点研究了波导DCN激光本征模(EH11模)在远场和近场的多阶高斯耦合效应,分析了DCN激光器的输出特性.理论计算的结果与实验数据基本吻合,并为EAST托卡马克远红外激光干涉仪系统的光学设计提供了必要条件

关键词: 波导DCN激光器, EAST超导托卡马克, 远场与近场, 高斯耦合

Abstract:

The principle and structure of DCN laserwere introduced in this paper.The EH11 mode approximation in the near field and the far field by Gaussian distributions and the beam property of DCN laserwere studied in detail. The theoretical work well fitted the experimental data.This work is important and necessary for further optical design for EAST tokmak FIR laser interferometer.

Key words: wave-guide DCN laser, EAST superconducting tokmak, far field and near field, Gaussian approximation
