PURPOSE:To efficiently obtain the maximum laser output by a method wherein the value of current to be flowed on solenoid coils is controlled by the monitor signal of a laser output. CONSTITUTION:The laser is made to oscillate laser beams by a fine laser tube 1; a laser tube 2 containing argon gas in its interior; electrodes 3 and 4; solenoid coils 5 around the fine laser tube 1; an output mirror 6 and a total reflection mirror 7, each constituting the optical resonator; and a power source 8, which actuates the laser tube 2 and the solenoid coils 5. A laser output 9 is separated into a main beam output 11 and a signal light 12 for laser output monitor by a beam splitter 10, and the signal light 12 is monitored by a detector 13. The current value of the solenoid coils 5 is also controlled automatically in such a way that the laser output 9 becomes the maximum one by the monitor signal. In such a way, even through the pressure of gas in the laser tube 2, etc., are varied and the optimum current value is changed, the gas pressure, the current value, etc., are automatically modified and the laser output 9 can be kept in the maximum one.
