Generation of frequency-tunable ultrashort optical pulses with liquid-core fibers.
Experimental generation of ultrashort, frequency-tunable optical pulses in liquid-core fibers is reported. Passage of high-energy optical pulses through a submillimeter liquid-core fiber reveals a quasi-linear frequency sweep. The subsequent use of a grating dispersion system and a spectral window shortens the Nd:YAG laser pulse duration from 45 ps to less than 2 ps. Based on spectral filtering after the grating pair, the wavelength of the generated short pulses is shown to be tunable.
