Yellow emission (573.5 nm) Ga 0.65 In 0.35 Plasers grown on GaAs 0.6 P 0.4 substrates by gas source molecular beam epitaxy

Abstract
The first current injection lasing action in AlGaInP/Ga0.65In0.35P heterostructures grown on commercially available GaAs0.6P0.4 substrates is reported. At 77 K, laser diodes exhibited threshold current densities of 900 A/cm2 with yellow stimulated emission near 5735 Å. This is the shortest current injection lasing wavelength ever achieved in a III-V compound semiconductor.
