Patent abstract

Narrow beam divergence semiconductor sources are operable to generate a beam having a substantially narrow beam divergence, an emission wavelength, and a substantially uniform beam intensity. The presence of an extended length mirror can help suppress one or more longitudinal and/or transverse modes such that the beam divergence and/or the spectral width of emission is substantially reduced.
