Photo-pumped lasing properties have been investigated in a CdSe/ZnSe/ZnSSE single quantum wells (SQWs) with the well-layer thickness (L W ) of 1, 2 and 3 monolayer (ML). At 20 K, the laser threshold for the SQW with L W = 1 ML was the lowest in spite of the smallest active layer thickness. The carri
