  • Gas laser with mode control
    Patent number: 6512781
    Abstract: A gas laser (1) has an optics system and a mode-masking diaphragm in the beam guiding chamber of the laser resonator. The optics system is adjustable between two settings in each of which any higher-order modes of the laser beam (3) are masked out. The Gaussian mode (9) can be generated in one of the two settings, and the ring mode (10) in the other setting. An appropriate control permits switching between Gaussian and ring modes depending upon the intended processing operation.
