Abstract

Electro-optic control is often used to reduce fluctuations in light beams. Until recently, it was thought that such a control mechanism could not reduce laser intensity fluctuations below the shot-noise limit. It is understood now that this limit can be circumvented with nonclassical or squeezed states of light. Indeed, in the past few years several experiments have demonstrated the use of active control for the generation of light with intensity noise below the shot-noise limit.
