  • Nested-cavity optical parametric oscillator for fast frequency tuning
    Patent number: 8542435
    Abstract: 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 ? with respect to the direction x. The value of ? 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.
