摘要：
A laser illumination beam generation system including a laser diode (LD) for producing a laser beam in response to a diode current supplied thereto, wherein the laser beam has a central characteristic wavelength. Diode current drive circuitry generates the diode current and supplies the same to the VLD. A high frequency modulation (HFM) circuitry modulates the diode current supplied to the laser diode, so as to produce a spectral side-band components about the central characteristic wavelength, and thereby reduces the coherence of the laser illumination beam as well as its coherence length. An optical multiplexing (OMUX) device receives the laser beam as an input beam and generates multiple laser beams therefrom and recombines the multiple laser beams so as to produce a composite output laser illumination beam having reduce coherence.
