Gas laser having a cylindrical discharge tube

Patent ·
OSTI ID:6827026
A gas laser having a cylindrical discharge tube is described. The laser consists of a glass casing or envelope sealed at each end by a metallic end cap, each of said end caps having a metal tubular component soldered therein to support a reflector or mirror to form an optical resonator, a capillary, which is secured in the casing adjacent one end cap, whose tubular component acts as an anode, to extend in the glass casing coaxially and is supported in the casing by at least one spring element at an axially displaced position, and a cold cathode, which surrounds at least a portion of the free end of the capillary and is in electrical communication with the other end cap, characterized by the improvement that the glass casing has a length of at least 40 cm so that the output of the laser is at least 10 mw.
