电光调Q脉冲激光外差研究

Study of Heterodyne of Q-switched Pulse Laser

采用高斯函数模拟电光调Q射频激励波导CO2 激光器输出脉冲激光的波形 ,在理论上研究了脉冲激光外差的波形及其傅里叶变换频谱成分 ,并在实验上测量了脉冲激光外差的波形及其傅里叶变换频谱 ,理论分析与实验结果一致。

In this paper, the pulse laser waveform output from RF excited waveguide CO 2 laser is fitted by Gauss function. The waveform of pulse laser heterodyne and its frequency spectrum of Fourier transform are studied in theory and experiment. The experimental results are consistent with that of theory.
