摘要： 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.

摘要： Nested-cavity optical parametric oscillator for fast frequency tuning including a source of pump radiation (fp), a non linear crystal situated within two resonant cavities for the signal and complementary radiations of respective optical lengths ls and lc. A doubly resonant resonator for a single pair of longitudinal signal and complementary modes is formed having a crystal of prismatic shape, the crystal (7) being moveable within the plane xz along a direction forming a non zero angle β with respect to the direction x. The value of β is fixed so that the movement of the crystal is accompanied by a change in the respective optical lengths ls and lc of the two resonant cavities in a ratio such that the double resonance condition between the longitudinal modes of each cavity is maintained.
