Abstract
Upconversion pumping of Er:YAlO3 in the 800 nm pump band is described. For pumping by cooperative energy transfer, over 160 mW of laser emission at 550 nm was obtained. The pump wavelength was 806.9 nm and the optical conversion efficiency is 17%. For photon avalanche upconversion pumping at 791.3 nm, 33 mW of laser output was produced.
