Gerald Hermann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and systems for laser processing a workpiece and methods and apparatus for controlling beam quality therein
    Publication number: 20060207977
    Abstract: Laser processing methods, systems and apparatus having a super-modulating power supply or pumping subsystem and high beam quality (i.e., brightness) are disclosed. The methods, systems and apparatus have significant benefits, improved operation characteristics and material processing capability over currently available methods, systems and apparatus. In at least one embodiment, the beam quality of a high power solid state laser is improved in the presence of thermal lensing. High power laser cutting, scribing, and welding results are improved with a combination of modulation and high beam quality while providing for improved processing speeds.
    Type: Application

  • Methods and systems for laser processing a workpiece and methods and apparatus for controlling beam quality therein
    Publication number: 20050094684
    Abstract: Laser processing methods, systems and apparatus having a super-modulating power supply (6) or pumping subsystem (5) and high beam quality (i.e., brightness) are disclosed. The methods, systems and apparatus have significant benefits, improved operation characteristics and material processing capability over currently available methods, systems and apparatus. In at least one embodiment, the beam quality of a high power solid state laser (2) is improved in the presence of thermal lensing. High power laser cutting, scribing, and welding results are improved with a combination of modulation and high beam quality while providing for improved processing speeds.
