Title:
SAFE-TO-EYES LASER TRANSMITTER WITH SINGLE RESONATOR CAVITY FOR PUMPING LASER AND OPTICAL PARAMETRIC OSCILLATOR
Document Type and Number:
Japanese Patent JP3217988
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laser system, which uses identical optical cavity for a pumping laser and an optical parametric oscillator.
SOLUTION: A transmitter, which is safe to the eyes of a human being, of a laser system 10 has a single resonator cavity 16 for both a pumping laser and an optical parametric oscillator 28. A neodymium-doped yttrium aluminium garnet (Nd:YAG) rod 22 provided with respect to a gain of a first-wavelength- light. This light is Q-switched 24, and then the intensity of the light is increased. The oscillator 28 converts the first-wavelength light into second wavelength light which does not injure the eyes.
