Title: Counter pumping a large mode area fiber laser

Abstract

A fiber optic assembly includes: a gain fiber configured to output signal light; a first taper configured to expand the signal light output by the gain fiber; and a reversing prism configured to receive counter-pumping light and output the counter-pumping light into the first taper. The first taper is further configured to direct the counter-pumping light towards the gain fiber.
