摘　　要：利用放大法进行约束放电激励千瓦级基模ＣＯ２激光器增益的测量，分析增益区的横向分布，得知此种激光器的增益值较高，增益区宽（与同类横流激光器进行比较），适合使用多折腔，并获得了优良的激光模式输出。According to design optimum and theoretical analysis of the CO2 laser,the techniques of the magnetically confined exciting,the transverse flow in two normal axes and multifolded cavity are employed.The transverse distribution of gain region and gain coefficient are analyzed and measured by means of amplification method.The results show that the gain coefficient of the laser is larger and the gain region is wider than ordinary transverse flow CO2 laser and the laser has the excellent TEM00 output mode with the multifolded cavity.
