Abstract

The present invention relates to a laser generator in which a laser beam is generated by energizing a laser medium and is amplified optically with optically amplifying mirrors, and the laser beam is received by a absorber, wherein a spacer 9 having a through hole 9a for passing therethrough the laser beam and at least one small second through hole 9b is arranged at a circumference of an absorber 7, and a cooling medium 12 circulates in the small second through hole 9b of the spacer 9. In this structure, if a scattering laser beam is generated at the circumference of the laser beam absorber, a parallelism of the optical amplifying mirrors is maintained so that the laser generator can generate the stable laser beam.
