Abstract
We report a demonstration of the first continuous-wave (cw) mid-IR microlaser operating at room temperature (RT). Our whispering-gallery-mode microlaser—operating at 2.71 μm—is based on a heavily erbium-doped high- ZBLAN microsphere optically pumped by a 980 nm diode laser; with a threshold pump power of .
