Abstract :
At room temperature (296K), continuous-wave (CW) operation of a blue laser diode has been achieved. The emission wavelength is 489.9nm, and the threshold current and voltage are 93mA (1.5kA/cm2) and 6.3V, respectively. The laser consists of a ZnCdSe/ZnSSe/ZnMgSSe single-quantum-well (SQW) separate-confinement heterostructure (SCH).
