Abstract

PURPOSE:To reduce the lowering of the output for the gas laser tube with which the lateral single mode by providing the metal pipe featuring the diameter of 1.7 times as large as the beam diameter of the laser to the area near the reflector of either side. CONSTITUTION:Thin tube 2 to grow the laser plasma is held by thick tube 1 at the center part of tube 1, and anode 3 and cathode 4 are provided to tube 2 and inside tube 1 respectively. Tube 2 features the inner diameter which is a little larger than the miximum threshold inner diameter with rather rough measurement, and plane mirror 6 is attached to one end of tube 2 via metal pipe 5. At the same time, concave mirror 7 is installed on the extended axis of the other end of tube 2. The inner diameter of pipe 5 is 1.7 times as large as the diameter of the laser beam.
