5000小时室温连续激射GaAs/AlGaAs双异质结激光器
CW operation over 5000 hours of GaAs/AlGaAs DH laser at room temperature
摘要
Abstract
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 lasers operate in single transverse mode and near single longitudinal mode. The degradation properties were studied and the lifetime for some lasers are over 5000 hours.
