The output of the laser beam is controlled so that the detector input may not exceed the maximum allowable input of the detector while the shielding plate is open. Moreover, the beam splitter, focusing lens, and detector are arranged so that the optical axis may be horizontal to the laser beam passing therethrough.

摘要： 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.
