Abstract:
1. A laser beam generation system having an integrated coherence length reduction mechanism, comprising: a flexible circuit having a first end portion and a second end portion; a laser diode mounted on said first end portion of said flexible circuit, for producing a laser beam having a central characteristic wavelength and a coherence length; diode current drive circuitry for producing a diode drive current to drive said laser diode and produce said laser beam; and high frequency modulation (HFM) circuitry, mounted on said first end portion of said flexible circuit, for modulating said diode drive current at a sufficiently high frequency to cause said laser diode to generate spectral side-band components about said central characteristic wavelength, and thereby reducing the coherence length of said laser beam.
