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 10):
A method of making a semiconductor laser, comprising:\n optionally forming a buffer layer on a substrate; and forming a plurality of quantum dot layer pairs, on the buffer layer if the buffer layer is present and on the substrate if the buffer layer is not present, as an active optical gain medium, the forming of each quantum dot layer pair comprising:\n forming a quantum dot layer having quantum dots exhibiting at least one of compositional inhomogeneity, size inhomogeneity, and density variation and having a broadband of gain profile and a lasing spectral bandwidth of at least 2 nm; and \n forming a barrier layer.
