An upconversion pumping scheme was used to produce cw laser action at 0.55 μm in YAlO3+ at temperatures up to 77 K on the 4S3/2→4I 15/2 transition. Two infrared dye lasers at 792.1 and 839.8 nm were used as the pump sources for stepwise two-photon excitation of the 4S3/2 upper laser level at 18 406 cm-1. The laser operates in the fundamental TEM00 mode, and a cw output power of ∼1 mW was achieved with ∼200 mW pump power from each infrared dye laser.
