Abstract

We report room-temperature continuous-wave upconversion laser emission on the green transition 4S3/24I15/2 in Er(1%), Yb(3%):YLiF4 at 551nm. Green laser operation was obtained for titanium–sapphire pump wavelengths continuously tunable between 955 and 974.5nm. Codoping with Yb3+ resulted in a more efficient excitation of the upper laser level by upconversion processes. The maximum green laser output power was 37mW at an incident titanium–sapphire pump power level of 1580mW at 966nm.
