            Abstract : 
The threshold current density (Jth) of blue-green CdZnSe/ZnSSe strained quantum well lasers is analysed using the laser theory established for III-V semiconductor lasers. Very good agreement between theory and the reported experimental Jth values is obtained over a wide temperature range from 77 to 273 K. The optimal Cd composition of a CdZnSe single quantum well active layer for obtaining a low Jth value at room temperature is in the range 0.25-0.30.
