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