摘要
The well-number dependence of the optical pumping threshold power for stimulated emission of GaInN multiple quantum-well(MQW) laser structures was investigated. The pumping threshold power for a three GaInN MQW sample was found to be as low as 33 kW/cm(2) at room temperature. The room-temperature pulsed operation of a five GaInN MQW laser diode (LD), whose number of wells was determined: based on the optical pumping experiment, was also demonstrated. The lowest threshold current density was 9.5 kA/cm(2). The lasing wavelength was 417.5 nm with a full-width at half-maximum (FWHM) less than the spectrum resolution of 0.2 run.
