Squeezed states in second-harmonic generation.

ABSTRACT

We consider the process of second-harmonic generation with the nonlinear crystal placed in a resonant cavity. Both the fundamental and the second-harmonic mode are shown to exhibit squeezing. An analysis is made for the general values of the ratio between the damping constants of the two modes. We suggest that second-harmonic generation is the most suitable system to use for an experimental observation of the squeezing effect.
