A simple and efficient laser intensity stabilization system was constructed based on an electro-optical modulator (EOM) and a photodetector. It is capable of reducing the laser intensity fluctuations to the shot noise limit within the range of Fourier frequencies from a few tens of hertz to a few megahertz. The achieved bandwidth of the laser control system is limited by the light handling capacity of the photodetector and spurious resonances of the EOM. We discuss the general approach to the design of the laser intensity stabilization system and its noise properties.
基于电光调制器（EOM）和光电探测器构建了一种简单高效的激光强度稳定系统。它能够在几十赫兹到几兆赫兹的傅里叶频率范围内将激光强度波动降低到散粒噪声极限。激光控制系统实现的带宽受光电探测器的光处理能力和电光调制器的杂散共振限制。我们讨论了激光强度稳定系统设计的一般方法及其噪声特性。
