ABSTRACT OF THE DISCLOSURE There is described a high speed axial flow type gas laser oscillator in which the flow rates of the laser gas inside the laser tubes will be more or less equal, in which the lengths of the recirculation paths from the laser tubes to the heat exchanger or cooler will remain approximately equal even if the number of tubes is increased or decreased. Further, the electrical discharges between the electrodes of the laser tubes and the heat exchanger are suppressed, reducing the loss of electric power used for injection and suppressing excessive heating of the laser gas, and, in addition, reducing the additional load on the heat exchanger or cooler. Also the removal and replacement of the electrodes in the laser tubes can be carried out easily without displacing the tubes in the axial direction. The vibrations in the blower which is used to circulate laser gas to the laser tubes are not transmitted to each of the tubes, and, moreover, it is possible to compensate for thermal deformation in the connections between the blower and the laser tubes. Additionally, the support plates which support both ends of the laser tubes are able to move slightly to compensate for expansion and contraction of the tie rods which are coupled to each support plate.
