High-power operation of a transverse-mode stabilised AlGaInp visible light (λ _<i>L</i> = 683 nm) semiconductor laser

Abstract

Continuous-wave (CW), stable fundamental-mode operation, up to 20 mW, was achieved with transverse-mode stabilised MOVPE-grown AlGaInP visible-light (λL = 683 nm) lasers. The CW threshold current was 67 mA and the external quantum efficiency was 41%. Up to 27 mW CW power was obtained from this laser diode.
