Paper Abstract

Low threshold operation of the 550 nm holmium laser is reported in a Ho3+:ZBLAN fiber pumped near 650 nm. The 550 nm transition has been pumped by an InGaAlP diode laser producing approximately 30 mW at 643 nm. Over 1.2 mW of green laser output and an optical conversion efficiency of 12% has been obtained. The threshold diode laser pump power was 3.5 mW launched.
