Abstract: A second harmonic generation apparatus provides a polarization element transmitting only light polarized in an extra-ordinary axis direction on the proceeding path of a second harmonic emitted from a resonator. The light polarized in the extra-ordinary axis direction is transmitted to a beam splitter, and a part of the polarized light is fed back to a feedback circuit, so that the temperature of a non-linear birefringent crystalline element inside resonator can be stably controlled and the output second harmonic can be stably produced.
