GAS LASER OSCILLATOR APPARATUS AND LASER GAS REPLACEMENT METHOD |
摘要 |
The gas laser oscillator apparatus of the present invention has laser gas sealed in a vacuum chamber under a decompressed condition lower than atmospheric pressure; a discharge means for exciting the laser gas; a blower means for blowing the laser gas; a laser-gas flow passage as a circulation passage of the laser gas between the discharge means and the blower means; and a gas compression means for discharging a predetermined amount of the laser gas from the laser-gas flow passage. The gas decompression means is structured on the application of Bernoulli's principle. The gas decompression means has a sequence for decreasing the ratio of air mixed into the laser gas below a predetermined level with use of a part of pressurized gas used in a laser processing machine or the gas laser oscillator apparatus. |
