PURPOSE:To output a high-energy laser beam by using a simplified structure without synchronous control by a method wherein laser oscillation is initiated on a discharge electrode common to an oscillation stage and amplification stage and thereafter the output is amplified in an optical resonance element. CONSTITUTION:A laser beam induced by an arc discharge between discharge electrodes 9a and 9b is thrown into resonance by an etalon 4 and mirrors 5 and 10, and the resultant laser beam is amplified by a spherical mirror 13 and front mirror 14 before being outputted. |
