Abstract
Ultrathin (∼ 1 μm) Cd(SeS) platelets are excited with a mode‐locked He–Ne laser and are shown to lase with a measured time delay of ∼ 10−9 sec. The measured delay agrees with the time required to redistribute optically generated electron‐hole pairs uniformly through the sample thickness and to the proper density (1018/cm3) to form excitons.Keywords
