Abstract

We demonstrate a low threshold 0.5 at.%-doped Er: YAG micro-NPRO with a short round-trip path length designed to reduce the effects of Energy-Transfer Upconversion (ETU) and reabsorption. A single-frequency laser output of up to 354 mW at 1645 nm was achieved using a 1470 nm LD with a pump power of 3.5 W through resonant pumping, corresponding to a slope efficiency of 44.6% and threshold pump power of 2.7W.
