摘　　要：报道了双通道可调谐电光调Q射频激励波导CO2 激光器 ,其中一通道是光栅选支电光调Q的脉冲激光输出 ,调Q脉冲重复频率 1Hz～ 10kHz可调 ,脉冲峰值功率为 15 0W ,脉冲宽度为 180ns。另一通道是光栅选支连续激光输出 ,可用压电陶瓷调节激光频率。同时分析了激光外差频率调谐范围 ,实验上获得最大脉冲激光外差频率调谐范围为 15 0MHz。An electrooptically Q-switched RF excited waveguide CO2 laser with two channels is demonstrated. The Q-switched pulse laser has been obtained from one of the channels with a grating. The peak power is 150 W and the pulse width is 180 ns. CW laser output has been obtained from the other channel, which can been tuned by a PZT. In addition, the tuning range of the laser heterodyne frequency is analyzed in theory and the largest tuning range is 150 MHz in experiment.
