Stimulated emission from Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te--CdTe heterostructures and Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te--Cd/sub 1-//sub y-italic/Mn/sub y-italic/Te multiple quantum well structures

We report the first observation of stimulated emission from Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te--CdTe and Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te--Cd/sub 1-//sub y-italic/Mn/sub y-italic/Te multiple quantum well structures. The active superlattice (SL) regions of these new laser structures consist of either 25 CdTe or 25 Cd/sub 1-//sub y-italic/Mn/sub y-italic/Te quantum wells alternating with 24 Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te barriers. The emission from the Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te--CdTe lasers occurs at 763--766 nm when optically pumped at T-italic = 25 K. The Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te--Cd/sub 1-//sub y-italic/Mn/sub y-italic/Te lasers emit coherent, visible red radiation (665--670 nm) when optically pumped at T-italic = 15 K at a peak power density of 2.00 x 10/sup 4/ W/cm/sup 2/. Stimulated emission from double-layer Cd/sub 1-//sub x-italic/Mn/sub x-italic/Te--CdTe heterostructures has also been observed.
