A simple and efficient laser intensity stabilizationsystem was constructed based on an electro-optical modulator(EOM) and a photodetector. It is capable of reducing the laserintensity fluctuations to the shot noise limit within the rangeof Fourier frequencies from a few tens of hertz to a few megahertz.The achieved bandwidth of the laser control system islimited by the light handling capacity of the photodetector andspurious resonances of the EOM. We discuss the general approachto the design of the laser intensity stabilization systemand its noise properties.
