    摘要: An optical wavelength converting apparatus comprises a semiconductor laser, which is capable of oscillating in a multiple longitudinal mode, and an external resonator for resonating a laser beam, which has been radiated out of the semiconductor laser and which serves as a fundamental wave. An optical wavelength converting device is located in an optical path of the fundamental wave, which has been resonated by the external resonator. A device feeds part of the fundamental wave, which has been resonated by the external resonator, back to the semiconductor laser. A wavelength-converted wave in a single longitudinal mode is thereby obtained, which wave has a high intensity and is stable.

    摘要: There is disclosed an optical frequency converter of a bulk resonator structure comprising a ring resonator or V-shaped resonator made of a nonlinear optical crystal. The converter is equipped with a means for returning a laser light emitted by a semiconductor laser resonating inside the resonator to the semiconductor laser. The ring resonator or V-shaped resonator is made small in size and compact. The converter is insusceptible to vibration and needs no adjustment. Returning laser light is produced at less locations. The loss of the output light inside the resonator is reduced. The second harmonic is generated at a high efficiency. Multiple reflection is produced inside the resonator to further enhance the efficiency of the generation of the second harmonic of the laser radiation. Also, the phase of the radiation can be made uniform. The optical density can be increased.

A collimated light beam having a sufficient cross sectional area is entered into the interface between a dielectric block and a thin metal film formed on the dielectric block at an angle that satisfies the conditions of total reflection. A light beam having a predetermined wavelength is selected from the light beam totally reflected at the interface to detect the distribution of optical intensities for the selected light beam by the wavelength selecting section capable of eliminating stray light.
