Abstract: PURPOSE:To realize a laser machining operation wherein the property of a laser beam is not changed by a method wherein a movement means which relatively moves, with reference to other individual means, a laser oscillation means which oscillates the laser beam by discharging and exciting a laser gas is provided and the distance from the oscillation port of the laser beam up to a machining point is always kept at a distance which is optimum for the machining operation. CONSTITUTION:A laser oscillator 1 is composed of a movable part 7 at the upper side and of a fixed part 8 at the lower side. The movable part 7 is provided with the following: a resonator 9 which generates a laser beam 3; a shutter 10; a return mirror 4; a machining head 11 which has housed a condensing lens; and a Z-shaft 12 which moves the machining head 11 up and down. It is driven and controlled by means of an NC apparatus or the like. A table on which a large plate has been placed is irradiated with the laser beam 3 which is generated by means of the resonator 9 via the shutter 10, the return mirror 4 and the machining head 11. At this time, the distance up to the machining head from the resonator is definite irrespective of the movement or the like of the movable part 7 because the laser oscillator is fixed to a machine. When the distance is set to a distance which is optimum for a machining operation, it is possible to keep an optimum state.
