Ridge waveguide AlGaAs/GaAs distributed feedback lasers with the cavity length of 820 ..mu..m were fabricated. The differential quantum efficiency was as high as 28%, and the power-dependent linewidth was more than an order of magnitude smaller than that of the 290 ..mu..m laser, which agrees with theory. The narrowest linewidth was 12 MHz at 6.2 mW.
