TLDR
It is demonstrated that the supercontinuum is compressible to a duration of 26 fs, and has a high degree of coherence between all the frequency components, and is a single pulse in the time domain.Abstract:
We demonstrate supercontinuum generation in a photonic crystal fiber with all-normal group velocity dispersion. Pumping a short section of this fiber with compressed pulses from a compact amplified fiber laser generates a 200 nm bandwidth continuum with typical self-phase-modulation characteristics. We demonstrate that the supercontinuum is compressible to a duration of 26 fs. It therefore has a high degree of coherence between all the frequency components, and is a single pulse in the time domain. A smooth, flat spectrum spanning 800 nm is achieved using a longer piece of fiber.read more

TL;DR: Numerical simulations in excellent agreement with the experimental results are used to discuss the scalability of the concept to the single-cycle regime employing active phase shaping, and it is shown that previously reported limits to few-cycle pulse generation from compression of SC spectra generated in conventional PCF possessing one or more zero dispersion wavelengths do not apply for ANDi PCF.

Limits of coherent supercontinuum generation in normal dispersion fibers
TL;DR: In this article, the authors studied the transition between coherent and noise-seeded incoherent continuum generation in all-normal dispersion (ANDi) fibers and showed that highly coherent supercontinua with spectral bandwidths of one octave can be generated with long pump pulses of up to 1.5 ps duration.
