Abstract: An experimental investigation was made of the main output and electrical parameters of cw diode lasers with an output of 1 W in the spectral range 808 nm at temperatures in the range 10 — 45°C. The width of the stripe contact was 100 mm. A numerical simulation yielded the values of the threshold current density, of the external differential quantum efficiency, and of the total efficiency of diode lasers generating multimode radiation. The results obtained made it possible to optimise the design parameters of the cavity.
