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150W,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150MHz。

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.
