Abstract
Abstract A coaxial CO 2 laser utilizing high-frequency excitation which has an advantage of the high-frequency excited type that it is small in size and is highly efficient as well as an advantage of the coaxial type that the beam mode has a high quality. The laser has a laser pipe (3) composed of a dielectric and two helical conductors that are adhered onto the outer peripheral surface of the pipe and that have the same pitch. A CO 2 laser gas flows through the laser pipe In the axial direction, and a high-frequency voltage is applied across the two conductors from a high-frequency power source (4).
