Abstract
Heterojunction injection lasers of (AlGa) As have been made with room‐temperature threshold current densities ∼3 times lower than previously reported devices emitting in the same spectral range. Fabry‐Perot structure lasers with Jth as low as 2530 A/cm2 emitting at ∼8800 Å are described. The improved performance is partly due to a very high optical gain coefficient resulting from a high doping level in an exceptionally narrow lasing region (0.8μ).Keywords
