Abstract

Employing Raman gain of optical materials is appealing for a variety of laser applications, to include fiber laser combiners. In order for a Raman combiner to be efficient, the Raman material must have high gain, low loss figure at 1st Stokes wavelength, and high loss figures at higher order Stokes wavelengths. This paper demonstrates an efficient double-clad fiber Raman combiner utilizing fused silica core as gain material with microstructured cladding designed with filtering properties implemented for suppression of higher order Stokes propagation in the core. Comprehensive study results of this Raman combiner will be presented.
