Abstract

In this contribution we show that second-harmonic generation (SHG) in a doubly-resonant resonator can be used to implement an efficient and compact source of bright squeezed light at the fundamental wave. The most promising concept for such a scheme is the use of a monolithic resonator, where the endfaces of the crystal constitute the mirrors. This approach allows for low losses, a large squeezing bandwidth and, most important, a strong nonlinear coupling of the modes.
