6kW单模CO_2激光器的输出光路和气体动力窗口

An output optical system and gas dynamic window for 6 kW level CO_2 lasers

本文叙述了一种用于6kW单模CO_2激光器的横向耦合输出光路和小孔径喷管气体动力窗口。它具有工作气体漏泄量小,能有效阻止空气分子向激光器工作腔内扩散,大大降低工作气体消耗等优点,且能显著改善输出光束模式。

A transverse output optical system and gas dynamic window of small diameter orifices for a 6 kW level CO2 laser is described. It has the advantages of less leakage of lasing gas and higher efficiency to prevent air molecules from diffusing into the laser cavity, and much lower consumption of lasing gas. It can also improve the laser beam modes.
