The configuration and technology for proton bombardment stripe geometric GaAs-GaAlAs DH laser is described briefly. The performances of DH laser under DC forward current were measured and analysed. The threshold current of most lasers is 50-150 mA. Differential quantum efficiency ηd is 30-70%. Some
