Abstract
We demonstrate the use of a commercial mode-locked and Q-switched Nd:YAG laser in photon-noise reduction experiments. There are many frequency bands wherein the photodetection of such a laser is shot-noise limited. By appropriately filtering the photocurrent produced in direct detection of light from an optical parameteric amplifier that is pumped with this laser, we have successfully generated twin-beam states of light. We demonstrate that such twin beams can be used to make measurements below the shot-noise limit.
