Abstract—

Low-frequency (flicker) noises of the intensity and frequency of diode laser (DL) radiation have been studied. A model of DL flicker noise and a method for minimizing flicker noise at which the relative photocurrent noise can be registered at a level of 5 × 10^–7 with an averaging time of 100 ms are proposed. The results obtained can be used in the development of DL-based gas-analytical equipment for measuring low gas concentrations.

二极管激光光谱中的闪烁噪声

摘要-

已经研究了二极管激光（DL）辐射强度和频率的低频（闪烁）噪声。提出了DL闪烁噪声模型和最小化闪烁噪声的方法，在该方法中可以将相对光电流噪声记录为5×10 ^–7的水平，平均时间为100 ms。获得的结果可用于开发基于DL的气体分析设备，用于测量低气体浓度。
