Abstract
Be-based II-VI semiconductors can be expected as a laser material with longer lifetimes than conventional ZnSe-based II-VI semiconductors. Continuous-wave operation in green-to-yellow spectral region was demonstrated with BeZnCdSe quantum-well laser diodes. The lasing wavelength of the fabricated green and yellow laser diode was 543 nm and 571 nm, respectively. Light output power over 50 mw has been confirmed with a low threshold current density.
