摘要
A CO2 laser device and a CO2 laser processing device for emitting a pulse laser having a high output and a stable beam diameter without depending on a repetition frequency. The CO2 laser device includes: laser gas being a CO2 laser medium; a near-concentric stable optical resonator in which a radius of curvature of at least one resonator mirror is set so as to be equal to a distance from an optical switch to the resonator mirror; an optical switch provided in the stable optical resonator; and transmission mirrors provided so that laser light generated from the stable optical resonator passes through the CO2 laser medium again.
