Method And Arrangement For Generating A Laser Beam Having A Differing Beam Profile Characteristic By Means Of A Multi-Clad Fibre
Patent No. EP2624031 (titled "Method And Arrangement For Generating A Laser Beam Having A Differing Beam Profile Characteristic By Means Of A Multi-Clad Fibre") was filed by Trumpf Laser UND Systemtechnik on Apr 8, 2011. The application was issued on Dec 13, 2017.
Patent Summary
A method and arrangement for generating a laser beam with different beam profile characteristics, where a laser beam is coupled into the inner fiber core or outer ring core of a double-clad fiber, and the beam profile is selectively controlled by adjusting the coupling conditions, such as beam diameter or angle of incidence, to achieve different beam profiles at the output. The arrangement includes a double-clad fiber and a switchable device that can be adjusted to couple the laser beam into the inner core, outer ring core, or both, to produce different beam profiles.
