Broadband light generation at similar to 1300 nm through spectrally recoiled solitons and dispersive waves

摘要

We experimentally study the generation of broadband light at similar to 1300 nm from an 810 nm Ti:sapphire femtosecond pump laser. We use two photonic crystal fibers with a second infrared zero-dispersion wavelength (lambda(Z2)) and compare the efficiency of two schemes: in one fiber lambda(Z2) = 1400 nm and the light at 1300 nm is composed of spectrally recoiled solitons; in the other fiber lambda(Z2) = 1200 nm and the light at 1300 nm is composed of dispersive waves.
