Abstract:
The invention applies to doubly resonant optical parametric oscillators comprising a non-linear crystal (4) through which pass a pump laser beam (fp), a signal beam (fs), and a complementary beam (fc), and a device (5) that totally or partially reflects said beams emanating from the crystal such that, after reflection, they generate between them a relative phase-shifting value ΔΦar for a given functioning mode independent of the signal frequency or complementary frequency, and is characterized in that the reflecting device (5) is a metallic minor, or a combination of two scattering mirrors and a multilayer dielectric mirror placed downstream.
