TL;DR: In this article, the spectral broadening of femtosecond Cr:forsterite laser pulses in tapered fibers was investigated. Butler et al. presented the results of their experiments devoted to the investigation of the femto-cond femtocond (F2F) laser pulses.

TL;DR: The hollow PCF is used as a high-peak-power Stokes field for coherent anti-Stokes Raman scattering (CARS) microspectroscopy, providing a dynamic range of nearly four decades for anti- Stokes signal detection, thus enabling time-resolved CARS studies of ultrafast relaxation processes on time scales from tens of femtoseconds up to tens of picose Conds.

TL;DR: Soliton self-frequency shift in a highly nonlinear photonic-crystal fiber is shown to enable an efficient wavelength conversion of 100-fs 70-MHz output of a solid-state ytterbium laser, allowing the generation of sub-100-fs laser pulses with a central wavelength tunable from 1060 to 1400 nm as mentioned in this paper.

TL;DR: In this article, a new regime of filamentation in water in tight focusing geometry, very similar to the so-called superfilamentation seen in air, was reported, where there is no observable conical emission and multiple small-scale filaments.

TL;DR: In this article, tight focusing of Cr:forsterite femtosecond laser radiation in water provides the unique opportunity of long filament generation, where the filament becomes a source of numerous spherical shock waves whose radius tends to saturate with the increase of energy.
