An ion laser comprises a main circuit for maintaining the discharge state of an ion laser tube, and an auxiliary circuit for adding an auxiliary DC voltage to a main DC voltage of the main circuit. The impedance of the auxiliary circuit is much larger than that of the main circuit when the ion laser tube has been discharging. At the starting of the ion laser tube discharge, a starter circuit drives the ion laser tube to discharge in accordance with an added voltage of the main and auxiliary DC voltages. Thereafter, the auxiliary circuit is substantially separated from the main circuit due to the difference of the impedances. As a result, surplus power which is not consumed in the ion laser tube is decreased to be negligible.
