Abstract
An experimental investigation was made of the main output and electric al parameters of cw diode lasers with an output of 1 W in the spectral range 808 nn at temperatures in the range 10 - 45 degrees C. The widt h of the stripe contact was 100 mu m. A numerical simulation yielded t he values of the threshold current density, of the external differenti al quantum efficiency, and of the total efficiency of diode lasers gen erating multimode radiation. The results obtained made it possible to optimise the design parameters of the cavity.
