  • System and method laser for processing of materials
    Patent number: 11975405
    Abstract: A multiple wavelength laser processing system is configured with a multiple wavelength laser source for generating a multiple wavelength coaxial laser processing beam. The laser processing system further includes a multiple wavelength optical system to deliver the coaxial laser processing beam to a laser-material interaction zone on the surface of a workpiece such that each of the a first and a second laser wavelengths in the processing beam impinge at least a portion of the interaction zone as respective first and second concentric laser spots. The multiple wavelength optical system includes a multiple wavelength beam collimator, a configurable chromatic optic, and a laser processing focus lens, wherein the configurable chromatic optic provides an adjustment to the relative focus distance of the first and second laser wavelengths.
    Type: Grant
