ABSTRACT:
A gas laser includes an inner tube filled with gas and having mirrors at its opposite ends to define a resonant chamber, an outer tube filled with gas and defining a gas reservoir for the gas in the resonant chamber, and electrodes for energizing the gas in the resonant chamber. The gas reservoir includes a pair of intermediate tubes coaxial with and between the inner and outer tubes. One of the intermediate tubes is open at one end facing one end of the laser and is joined at its opposite end facing the opposite end of the laser to the outer tube. The other intermediate tube is open at its end facing the opposite end of the laser and is joined at its end facing the one end of the laser to the inner tube, whereby the pair of intermediate tubes divide the reservoir into a plurality of annular spaces defining a zigzag path between the opposite ends of inner tube.
