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 3):
The semiconductor laser of  claim 1  wherein the laser emits laser light from its edge and is optically pumped with at least one light source having a shorter wavelength than the emitted laser light, the semiconductor laser further comprising:\n a top waveguide layer above the active optical gain medium and a bottom waveguide layer below the active optical gain medium; and \n a top cladding layer and a bottom cladding layer for the top waveguide layer and bottom waveguide layer respectively, each cladding layer being on the side of the respective waveguide layer opposite that of the side adjoining the active optical gain medium, the cladding layers having a lower refractive index than that of the waveguide layers.
