可调谐TEA CO_2序列带激光放大中光栅对寄生振荡的抑制

Suppressing the Parasitic Oscillation in the Tunable TEA CO_2 Sequence Laser Amplifier

本文讨论了可调谐TEACO2 序列带激光放大级中的寄生振荡的成因 ,提出了一种在放大级中放置一闪耀光栅来抑制放大过程中产生的常规带寄生振荡的方法。经实验验证 ,结果表明该法有效可行。

This paper analyzes the cause of parasitic oscillation in the tunable TEA CO 2 sequence laser amplifier.A method for suppressing the regular bands parasitic oscillation caused in the sequence laser amplification by placing a diffraction grating is introduced.The experiment is proved the method is efficient and executable.
