High-power fiber laser with a polarizing diffraction grating milled on the facet of an optical fiber
Vanek M, Vanis J, Baravets Y, Todorov F, ctyroky J, Honzatko P
Opt Express
. 2017 Jan;
24(26):30225-30233.
PMID: 28059298
We milled a sub-wavelength diffraction grating on the facet of a large mode area fiber. The diffraction grating had different reflectivities for TE and TM polarized light. It was tested...
