An electro-optical Q-switched RF-excited Z-fold CO(2) waveguide laser was designed, which can output a Q-switched laser and a cavity-dumped laser synchronously. The build-up time method is presented to stabilize the laser frequency. A closed-loop control system was designed to keep the laser oscillating at the peak of the gain curve by measuring the pulse build-up time continuously and controlling the cavity length. In the experiment, the variations for the pulse build-up time and cavity-dumped laser output power with time were recorded in a period of time. The frequency fluctuation is less than ±16 MHz.
设计了一种电光调Q射频激励Z折叠CO₂波导激光器，它能够同步输出调Q激光和腔倒空激光。提出了积累时间法来稳定激光频率。设计了一个闭环控制系统，通过连续测量脉冲积累时间并控制腔长，使激光器在增益曲线的峰值处振荡。在实验中，记录了一段时间内脉冲积累时间和腔倒空激光输出功率随时间的变化情况。频率波动小于±16兆赫兹。
