Abstract

We report the results of pump and probe transmission and magneto- stimulated emission experiments performed in ZnCdSe/ZnSe multiple quantum wells of different well width and composition. The pumping conditions for the excitonic bleaching and the stimulated emission are directly correlated to the exciton stability in different samples. A transition from excitonic to free carrier lasing is observed by finely tuning the injection rate around the exciton ionization threshold.
