| 摘 要： | 采用双光栅谐振腔和增长放电增益区，进行了TEA CO2激光器弱线输出特性研究。在CO2,N2,He气体体积比为0.16∶0.21∶0.63，总压强为57.3 kPa情况下，获得6条11 μm波长附近弱线(序列带和热带)激光输出，谱线脉宽为400 ns左右。研究了011-030带的P19线的输出波形和能量，结果表明：谱线输出能量随光栅中心的位移变化而变化，当光栅中心在放电区中心轴线上时输出最强,最大输出能量达几百mJ。

| Abstract: | The study of the TEA CO2 weak lines were carried out by adopting two grating cavities and lengthening the gain region of the discharge chamber. Six near 11 μm weak lines (sequence band and hot band lines) were obtained successfully with 16% CO2, 21% N2, 63% He (volume ratio) at total pressure of 57.3 kPa. The pulse width of weak lines is 400 ns around. While the center of grating is on the axis of the discharge chamber, the maximal energy output appears, which is several hundred mJ. |
