The nonlinear propagation of a laser beam in a hollow-core capillary is studied by solving
the spatiotemporal nonlinear propagation equation. Although we assume to initially couple …

In this Letter, we show theoretically that the nonlinear photoionisation process of a noble gas
inside a hollow-core photonic crystal fibre can be exploited in obtaining broadband …

Dispersive waves (DWs) radiation in optical fibers allow to excite frequencies in spectral
regions that are otherwise difficult to access. However, the resonant emission is weak and …

We demonstrate numerically and experimentally that intense pulses propagating in gas-
filled capillaries can undergo localization in space and time due to strong plasma …

The resonance band in hollow-core photonic crystal fiber (HC-PCF), while leading to high-
loss region in the fiber transmission spectrum, has been successfully used for generating …

Tunable mid-infrared dispersive waves are generated in a birefringent fluorotellurite
microstructured fiber (FTMF) pumped by a 1560 nm femtosecond fiber laser. The FTMF have …

Efficient supercontinuum generation demands for fine‐tuning of the dispersion of the
underlying waveguide. Resonances introduced into waveguide systems can substantially …

The underlying mechanism of broadband dispersive‐wave emission within a resonance
band of gas‐filled anti‐resonant hollow‐core fiber is studied. Both numerical and …

Ultrashort laser pulses, featuring remarkable spectral tunability, are highly demanded for
nonlinear light-matter interactions in a variety of molecules. Here, we report on the …

We present accurate measurements of carrier-envelope-phase effects on ionization of the
noble gases with few-cycle laser pulses. The experimental apparatus is calibrated by using …
