US Patent:

7054341, May 30, 2006

Filed:

Feb 19, 2003

Appl. No.:

10/505070

Inventors:

Gerald Francis Hermann - Westland MI, US
Thomas Robert Kugler - Williamston MI, US
Mohammed Naeem - Rugby, GB
Keith Withnall - West Haddon, GB
Walther Goethals - Best, NL
David M. Filgas - Newbury Park CA, US

Assignee:

GSI Group Ltd. - Warwickshire

International Classification:

H01S 3/10

US Classification:

372 26, 372 31

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.
