Abstract:
1. A coherent supercontinuum source, comprising: a low-noise fiber-based pulsed source arranged in combination with a highly non-linear material, said low-noise fiber-based source comprising a mode locked fiber oscillator, said fiber-based pulse source generating an output comprising short optical pulses having a pulse width <1 ps at a central wavelength >1700 nm, said highly non-linear material receiving said output from said low-noise fiber-based pulse source and generating a coherent supercontinuum having a spectral bandwidth of at least one-half octave between two −30 dB points; and a low-noise pump source to pump said low-noise fiber-based pulsed source, wherein said supercontinuum is characterized by having a first order nearest neighbor coherence value of at least 0.7 at two locations within said spectral bandwidth.
