CO_2大功率气体激光器使电的控制信号转变为光束功率信号时严重失真,主要是在脉冲工作态时,激光脉冲极大地依赖重复脉冲频率,占空因数、放电电流、激光气体混合比以及激光器的调制状态。对于精密材料加工来说,掌握并能再现重要的光束参数,如 CO 2 high-power gas lasers make the control signals of electric power become serious distortions when they are converted to the power signals of the light beams, mainly in the pulse mode, the laser pulses greatly depend on the repetition pulse frequency, duty ratio, discharge current, laser gas mixture ratio, Modulation status. For precision material processing, master and reproduce important beam parameters such as
