RADIATIONAL SYSTEM OF LASER GENERATOR

摘要

A discharge system for a gas laser oscillator (a) includes outer tubes (a1), inner tubes (a2) coaxially arranged with the outer tubes, a pair of cathode support members (1,1'), and an anode support member (2) disposed between the two cathode support members. The support member is made of conductive material so as to be used as an electrode. The support member has an inner tube support in which an inclined circular surface is formed with a narrow part at its center portion between two inner tubes. After inner tubes and outer tubes are fitted to the support member, a cap (6) comprising a sealing member (5) and two O-rings (4) is fitted onto the tubes and the support member.
