Abstract :
Summary form only given. Optical parametric amplifiers (OPA) have been demonstrated previously as a system capable of generating strongly squeezed states. The output from these systems is typically a "vacuum squeezed state" where the beam has no coherent amplitude. Such squeezed states may be used to improve the performance of optical measurements limited by quantum noise, or as reported, to facilitate QND measurements. The OPA is a monolithic MgO:LiNbO/sub 3/ crystal polished and coated on one side.
