Patent ID: 8861073

Claim:
An optical fiber delivery system for delivering optical short pulses, comprising: a chirped pulse source for emitting an up-chirped optical short pulse having high peak power, the chirped pulse source including: an ultrashort optical pulse source for emitting an ultrashort optical pulse; and a positive group-velocity dispersion generation unit for providing positive group-velocity dispersion to the ultrashort optical pulse emitted from the ultrashort optical pulse source, and outputting the ultrashort optical pulse as the up-chirped optical short pulse that is smaller in peak power than the ultrashort optical pulse; an optical waveguide unit for delivering the optical short pulse emitted from the chirped pulse source; a negative group-velocity dispersion generation unit for providing negative group-velocity dispersion to the optical short pulse exited from the optical waveguide unit; and an optical fiber for delivering the optical short pulse exited from the negative group-velocity dispersion generation unit, along a desired distance, wherein the optical short pulse emitted from the chirped pulse source is adapted to be exited, from the optical fiber, as a down-chirped optical short pulse.
