Optimum stimulated light powers from GaAs injection lasers

The total stimulated light power obtainable from GaAs injection lasers is optimized by varying reflection coefficient, laser length, and width. The laser performance is assumed to be limited by heating, and a given temperature rise is taken as a constant parameter of the optimization procedure. Two cases are considered: 1) operation with short pulses at low duty cycle, and 2) continuous operation. For both cases optimum reflection coefficients are obtained. Case 2) leads to optimum values for laser length and width, case 1) to favorable length values only.
