A coaxial-type carbon dioxide gas laser includes an oscillator comprising a gas inlet for introducing gas into a discharge tube through a gas supply chamber having a hollow cylindrical body which serves to disturb the gas flow and orientate the gas toward the discharge tube via a space defined between the discharge tube and the hollow cylindrical body. The gas which has been subjected to an electrical discharge is drawn out of the discharge tube through a chamber and a gas outlet connected therewith. A pair of anode and cathode electrodes are disposed adjacent to the ends of the discharge tube. One of the electrodes is mounted on the gas supply chamber and is annular in shape. The gas supply chamber and the hollow cylindrical body jointly define a gap for passage therethrough of the gas fed from the gas inlet toward the discharge tube via the space. The space is large in cross section than the gap. The discharge tube has an inside cross-sectional area smaller than an outside cross-sectional area and larger than the cross-sectional area of the gap.
