K. Katayama et al., LASING CHARACTERISTICS OF LOW-THRESHOLD ZNSE-BASED BLUE GREEN LASER-DIODES GROWN ON CONDUCTIVE ZNSE SUBSTRATES/, Applied physics letters, 73(1), 1998, pp. 102-104
Room temperature continuous wave operation of ZnSe-based blue/green la
ser diodes grown homoepitaxially on conductive ZnSe substrates with th
reshold current densities as low as 176 A/cm(2) has been demonstrated.
This is the lowest reported threshold among all short wavelength lase
rs in the blue/green region. Lifetimes at room temperature of up to 2.
1 h have been obtained for lasers with pre-existing defect densities l
ower than 3 x 10(4) cm(-2). (C) 1998 American Institute of Physics.
