We report experiments and numerical simulations on the self-focusing and filamentation of ultraintense femtosecond Airy waveforms in water. The accelerating property of Airy waveforms results in the generation of distinct features in the angularly resolved spectra of forward-propagating supercontinuum emission. Fitting these features with appropriate phase-matching conditions allows for the qua...

The generation of supercontinuum (SC) is the result nonlinear effect and dispersion. In order to better understand broadening mechanism SC, this paper studies influences various dispersions on SC evolution in photonic crystal fiber.

Ultra wideband CW pumped optical supercontinuum source Yue Song Keyword: supercontinuum, ultra wide optical source, nonlinear optical effects, continuous wave pump, ring cavity laser; Optical supercontinuum (OSC) laser source is a new generation wideband laser which has various commercial applications such as telecommunication, biomedicine, and optical sensing systems. However the high costs of...

Supercontinuum spectrum generation is a process in which laser beam femtoseconds and high power (kilowatts) converted into broad-spectrum of light after passing through specific environment. Of course, achieving this range comes with many limitations. In paper, photonic crystal fibers are used as substrate for input pulse due to the ability control dispersion loss, creating single-mode operatin...
