ABSTRACT: A very-high-power, single-mode GaAlAs triple-quantum-well (TQW)
laser with a novel real refractive index guided structure has been
developed. The maximum output power of 720 mW CW and single transverse-
and longitudinal-mode operation up to 600 mW CW have been achieved in a
single-element device. This excellent mode operation is attained by
using the real refractive index guided structure with a GaAlAs
current-blocking layer which gives a low effective refractive index
step, suppressing the spatial hole-burning effect in the high-power
range
