Topic: Characterization of multiclad fibers: approaches to measure the beam divergence angle and its degradation in the fiber

Presenter: Dörte Schönfeld

Dörte Schönfeld studied physics at Friedrich Schiller University Jena, Germany. She graduated on integrated optics and surface analysis in 1996 joining the photonics department of Fraunhofer IOF Jena. Since 1997 she is with Heraeus Quarzglas GmbH & Co. KG. At first, she focused on metrology for microlithography lens blanks, especially interferometry and stress birefringence, for which she was awarded with the first prize of the Heraeus Innovation Award in 2013. In 2015 she changed into the R&D Team Specialty Fiber Optics as project leader of an EU-funded project for the development of a rare earth doped bulk silica for laser fibers. Current studies are concentrated on the development of metrology for fused silica preform and fiber characterization.

Abstract:

Multiclad fibers with un-doped silica core and alternating highly fluorine doped and undoped silica claddings are a new standard for high power laser beam transmission, because they allow tailoring the output beam profile of a single laser source and adjust the laser beam to the application. For these fibers it is important to preserve the divergence angle of the launched light in the different light-guiding sections. In this work, we compare two possible measurement concepts. Results for multiclad fibers are discussed. Finally, it is concluded that a modified far field method with adjusted pinholes is most suited for our objective.
