Abstract:
A semiconductor visible laser with broadband emission and reduced speckling is provided. Conventional lasers with narrow spectral emission cause undesired speckles. The invention reduces laser speckles by producing a broadband laser emission. The laser comprises a multitude of quantum dot layers having quantum dots that have inhomogeneity in size, density, or composition. Methods of constructing such a laser are also provided.

Claim (Index 1):
A semiconductor laser, comprising:\n a substrate; an optional buffer layer on the substrate; and an active optical gain medium on the buffer layer if present, or on the substrate if the buffer layer is not present, the active optical gain medium comprising:\n a plurality of quantum dot layer pairs, each pair comprising a quantum dot layer and a barrier layer, the quantum dot layer having quantum dots exhibiting at least one of compositional inhomogeneity, size inhomogeneity, and density variation and enabling the emission of laser light with a spectral bandwidth of at least 2 nm.
