CO2 laser device and CO2 laser processing equipment

摘要

Beam diameter without depending on the repetition frequency at high output is I get a CO2 laser device and a CO2 laser processing apparatus emits a stable pulse laser. A laser gas G to be CO2 laser medium, at least one radius of curvature of the resonator mirror, the near both hearts type is installed so as to be equal to the distance to the resonator mirror from the optical switch stable optical resonator stabilized I comprises an optical switch provided in the optical resonator, and a transmission mirror 51 to 56 which is provided to the laser beam 41 passes through a CO2 laser medium again generated from a stable optical resonator.
