We report a realization of room temperature lasing threshold of 1 W in GaInP microdisk containing a few self-aggregated InP/GaInP quantum dots (QDs) grown by metal-organic vapor phase epitaxy. InP/GaInP QD microdisk cavities emitting in the spectral range of 700-800 nm and having the size of 2m, free spectral range of 35 nm and quality factors Q 4000 were formed by wet chemical etching. Low dot density (2 m(-2)) and large dot size (150 nm), suggesting a single dot lasing and maximum overlap of QD and cavity mode, were achieved using deposition of 3 ML of InP layer at 700 degrees C.
