Laser processing head () of the present disclosure includes housing (), transparent protector (), and temperature sensor (). Housing () includes an optical path of processing laser light (LB). Transparent protector () is detachably fixed to housing (), passes processing laser light (LB), and suppresses dust of work material (W) entering into housing (). Here, the dust is generated from the work material (W) irradiated with processing laser light (LB). Temperature sensor () detects the temperature of transparent protector ().

Laser processing head and laser processing system using same

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.

Gas laser oscillator apparatus and laser gas replacement method

Gas laser oscillator

A laser oscillation apparatus includes: a laser cavity unit for generating laser light by being provided a voltage and optically amplifying the generated light by means of a pair of mirrors; and a DC power source for supplying the voltage required for generating the laser light to a pair of discharge electrodes of the cavity unit. Each of a cathode and an anode of the DC power source is grounded via a grounding resistor.
