  • Gas lasers including heat exchangers
    Patent number: 9306361
    Abstract: A gas laser includes a fan for producing a flow of a laser gas and a heat exchanger including multiple heat exchanger pipes. The heat exchanger further includes two end plates to which the multiple heat exchanger pipes are secured at the opposing ends thereof. The two end plates include openings for supplying a heat exchanger fluid to the multiple heat exchanger pipes. The multiple heat exchanger pipes extend substantially transversely relative to a flow direction of the flow of laser gas.
    Type: Grant

  • LASER PROCESSING MACHINE WITH AN OPTICAL DIAPHRAGM
    Publication number: 20080314880
    Abstract: A laser processing machine includes focusing optics that intermediately focus the laser beam inside a beam guiding cavity. The laser processing machine also includes an optical diaphragm disposed in the area of the intermediate focus for forming the laser beam, the diaphragm aperture diameter being about 1.2 to about 2.5 times larger than the 99% beam diameter of the intermediately focused laser beam.

  • Laser with device for modifying the distribution of laser light intensity across the laser beam cross-section
    Patent number: 6539045
    Abstract: A gas laser includes a control to modify the distribution of the intensity of the laser light over the laser beam cross section produced in the lasing gas within at least one laser tube by at least two electrodes and a voltage supply unit by means of which a voltage can be fed to electrodes. A discharge area forms in the lasing gas and this can be affected by adjusting the amplification profile of the laser over the excitation cross section of the laser tube.

  • 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.
