Abstract
A wide-band power control system based on an electro-optical modulator and transimpedance amplifier has been constructed. It is capable of reducing laser intensity fluctuations to the shot noise limit over the range of Fourier frequencies from a few tens of Hz to a few MHz with the low boundary set by the light handling capacity of a photodetector and the upper boundary imposed by the spurious resonances of a given electro-optical modulator. We discuss a general approach to the design of laser intensity control system and its noise properties.
