碘分子532nm激光稳频系统的参数优化

The parameters optimization of Doppler-broadened iodine at 532nm Nd∶YVO_4 laser frequency stabilization

根据FM光谱通过吸收介质后 ,经检测、相干解调的理论分析 ,建立了线性吸收稳频的数学模型 ;得到不同调制频率和调制度的误差控制信号。由此给出用于碘分子线性吸收激光稳频的最佳调制频率和最佳调制度。

The mathematical model of linear absorption frequency stabilization is established. According to the model for FM laser passing the absorber,the error signal of different modulation frequency and modulation index is obtained. Then the optimal modulation frequency and the optimal modulation index is given.
