  • Gas laser device
    Patent number: 8116348
    Abstract: A gas laser device is presented that produces a near diffraction limited round beam exiting the discharge vessel. Through the use of a simple focusing system, additional waveguide strip and a spatial filter in conjunction with the new asymmetric hybrid planar waveguide resonator, a round diffraction limited beam can be produced exiting the discharge vessel. Furthermore, a second and very similar design is presented that allows for spatial filtering to take place directly outside of the discharge vessel, thereby enabling filtering of the beam to be an added option.
    Type: Grant

    Date of Patent: February 14, 2012
