Hollow cathode type metallic-ion laser
专利汇可以提供Hollow cathode type metallic-ion laser专利检索，专利查询，专利分析的服务。并且PURPOSE:To keep all oscillating beams under an optimum state by the pressure of encapsulated He on practicability as a laser pipe, and to continue the operation of a laser by specifying the relationship of a space between anode pins and the bore diameter of a hollow cathode in the hollow cathode type metallic-ion laser. CONSTITUTION:Anode pins for a metallic-ion laser are arranged so that the relationship of a space L between the anode pins and the bore diameter D of a hollow cathode satisfies L=10D1/2. When negative glow discharge is started, the whole cathode is heated by discharge heat, metallic vapor is fed and diffused into the hollow cathode 2 through a slit 21 between each anode pin 1, and laser oscillation is started. When the temperature of a pipe reaches to the state optimum for the operation of the laser, the temperature of the cathode 2 is controlled by air cooling in order to bring metallic vapor pressure in the pipe to a stationary state. The width of the slit 21 is set to approximately half hollow-cathode dark section length in the starting of the operation of the laser on the optimum pressure of He, and an intrusion to a metallic reservoir 3 of plasma is prevented. Cd adhering on the inner surface of the hollow cathode 2 is sputtered by He ions at that time, and the inner surface of the cathode 2 is under an initial state at all times. Metallic vapor is distributed uniformly extending over the whole region of a cathode bore.，下面是Hollow cathode type metallic-ion laser专利的具体信息内容。
