    Gail Overton
    One of the challenges in any materials-processing application that uses high-power, high-brightness lasers (kilowatt power levels) is "focus shift"-the shift in focus position...

    TruLaser 1030 cutting system offers high technology at a low price

    LFW Staff
    Trumpf's TruLaser 1030 features all the benefits of Trumpf technology. It combines a rugged drive system and machine construction with a TruCoax 2 KW diffusion cooled RF laser...
    FIGURE 1. The annular discharge design uses an increased discharge area and opens the discharge gap to allow free-space propagation rather than waveguiding, which reduces concentricity and alignment requirements and results in output powers similar to a planar waveguide with the same electrode footprint.

    Novel design approach benefits CO2 laser users

    Compact free-space annular radio-frequency discharge results in a robust, near-diffraction-limited, multikilowatt laser.
