Erbium doped ZBLAN fiber laser operating in the visible-feasibility study

Abstract

This work is focused on developing an all-fiber green laser in hybrid geometry, based on a combination of Er:ZBLAN active fiber and silica fiber-based passive components of an optical resonator and deploying Fiber Bragg Gratings (FBGs) as highly selective mirrors for the green spectral range. The scope of work covers a fundamental spectroscopic characterization of Er:ZBLAN samples, determination of key spectroscopic parameters, modelling the lasing properties and lasing experiments in different pumping geometries.
