Abstract

In this paper, we report a diode pumped Tm,Ho:GdVO₄ laser operating at cryogenic temperature, which has 3.5W of 2-μ m output. Tm,Ho:GdVO₄ crystal has very stronger and broader absorption spectrum than Tm-Ho co-doped YLF and YAG, and very favorable for diode pumping. The fiber-coupled laser diode of 808nm(core diameter 0.4mm,N.A 0.22) is a pumping source to end-pumping Tm,Ho:GdVO₄ crystal. The optical-optical conversion efficiency of 34% and threshold pump power of 0.79 W has been achieved. The laser design and laser performance is described.
