Optimization of Noise Correlated Single-mode Laser Output and Its Stability

根据输入信号的单模激光增益系统的光强相对涨落C(0)和输出功率信噪比SNR,定义了物理量K,以描述激光系统的整体输出性质。分析了K随泵噪声强度Q的变化关系,对系统的整体性质进行优化选择,给出了最佳优化选择条件。

Based on the relative fluctuation C(0) of light intensity and signal-noise ratio (SNR) of the output of the single-mode laser gain system of input signal,the physical value K is defined to describe the overall output of the laser system.The variation correlation of K with pump noise intensity Q is analyzed.The overall properties of the system is optimized,and the optimal conditions are given.
