A high efficiency 1343 nm Nd:LuVO₄laser in-band pumped at 916 nm

Abstract

A high efficiency 1343 nm Nd:LuVO4 laser in-band pumped at 916 nm is demonstrated for the first time. By using an all-solid-state Nd:LuVO4 laser operated at 916 nm as the pump source, 1.12 W output power was obtained with 2.3 W absorbed pump power. The corresponding slope efficiency was 61.9%, which is the highest among Nd:LuVO4 lasers operating at 1343 nm, to the best of our knowledge. The fluctuation of the output power was better than 2.3% in the given 30 min. The beam quality M2 factor value was equal to 1.13 at the maximum output power.

High-efficiency Nd:LuVO4 laser at 1343 nm recycling-pumped by a laser diode at 916 nm

“…In 2013, a Nd:LuVO 4 laser pumped by a diode-pumped 916nm Nd:LuVO 4 laser achieved an output power of 1.12 W at 1,343 nm. This corresponds to a slope efficiency of 61.9% relative to the absorbed pump power [21].…”
