Abstract
The invention applies to doubly resonant optical parametric oscillators comprising a non-linear crystal () through which pass a pump laser beam (f), a signal beam (f), and a complementary beam (f), and a device () that totally or partially reflects said beams emanating from the crystal such that, after reflection, they generate between them a relative phase-shifting value ΔΦfor a given functioning mode independent of the signal frequency or complementary frequency, and is characterized in that the reflecting device () is a metallic minor, or a combination of two scattering mirrors and a multilayer dielectric mirror placed downstream.
