We have studied the photoluminescence properties of as-grown GaAs₁ˍₓNₓepitaxial layers grown on GaAs containing 0.6%, 1.77%, and 2.8% nitrogen. We found laser emission from thick (d>200 nm) GaAs₀.₉₇₂N₀.₀₂₈ layers exhibiting the characteristic lasing properties of random lasers. This is unusual because random lasers have so far only been associated with highly disordered or random media. We believe that high gain in combination with structural inhomogeneities that are evident in these...[Show more]
