Abstract
By employing both steady state and picosecond excitation spectroscopically, we show that the origin of gain and laser action in optically pumped (Zn, Cd)Se/ZnSe quantum wells in the blue-green is of excitonic nature. Among other observations we find that stimulated emission readily occurs when excitation takes place resonantly into the n = 1 HH exciton absorption line.
