Abstract
PURPOSE:To generate spatially uniform plasma, and improve cooling efficiency, by arranging a dielectric wall with conductivity higher than plasma, which wall faces dielectric being a microwave incident window, and making another part of the microwave circuit come into close contact with the dielectric. CONSTITUTION:By intense microwave electromagnetic field generating so as to concentrate in the vicinity of ridges 21, 22, laser gas sealed in a discharge space 26 is subjected to discharge breakdown, plasma is generated, and laser medium is excited. The discharge space 26 is formed between a conductor wall 24 and dielectric 25 which is arranged so as to face the conductor wall 24 and serves as an incidence window. In this space, microwave discharge is generated, and microwave enters only from one side surface of the plasma. Thereby, enabling the discharge by a desired microwave mode. The dielectric 25 is arranged in the manner in which a surface opposite to the surface facing the conductor wall 24 is in close contact with the ridge 22 constituting another part of the microwave circuit. Thereby, preventing the saturation of laser output caused by the temperature rise of laser gas, and obtaining a gas laser equipment of high efficiency and large output.
