LASER OSCILLATOR AND LASER WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a laser oscillator which tan take out two stable laser beams and a laser working device using the oscillator. SOLUTION: A pair of mirrors in an optical resonator, which constitute the laser oscillators 1, 1a and 1b, are set to be output mirrors 5, 5a, 5b, 6, 6a and 6b.
