基于六温度模型速率方程理论,建立了系统计算光栅调谐TEA CO2激光器动力学特性的理论模型。利用该模型举例计算了光栅调谐TEA CO2激光器的各种输出特性。计算中,激光器的增益体积为0.9 L,闪耀光栅的光栅常数为120 line/mm,闪耀角为30°,激光混合气体气压为61??3 kPa,温度为300 K,采用光栅零级作为耦合输出。计算给出了如下结果
Abstract
Based on the theory of six-temperature model rate equation a theoretical model on calculating the kinetic characteristics of a grating-tuned TEA CO2 laser is given. As an illustration, the output characteristics of a grating-tuned TEA CO2 laser is calculated out by this theory. In the calculation, a grating with a brazing angle 30° and 120 grooves per millimeter is used. The laser is assumed to be of an active volume 0.9 litter and total gas pressure 61.3 kPa under temperature 300 K. By numerical calculation, the following results are obtained
