It is interesting to pose the question: How best to design an optomechanical device, with no electronics, optical cavity, or laser gain, that will self-oscillate when pumped in a single pass with only a few mW of single-frequency laser power? One mig

Soliton dynamics can be used to temporally compress laser pulses to few fs durations in many different spectral regions. Here we study analytically, numerically and experimentally the scaling of soliton dynamics in noble gas-filled hollow-core fibers

Gas-based systems (e.g. based on hollow-core fibres) are extensively used over a wide spectral range to temporally compress ultrashort pulses. Recent progress in solid-state lasers and compression schemes has enabled the generation of sub-femtosecond

Soliton dynamics can be used for compressing optical pulses to few fs durations over a wide spectral range, and can be conveniently scaled in gas-filled hollow-core fibre by suitable design of the fibre structure and choice of gas [1] , [2] . In this

The optical properties of hollow-core photonic crystal fibre (HC-PCF) can be conveniently tailored by modifying the transverse microstructure and selecting the species and pressure of the gas filling the hollow regions. Additionally, absorption of li

The evolution of a recombination-driven density depression in a krypton-gas-filled capillary, photoionized at MHz repetition rates, is interferometrically tracked. The msec-long buildup increases in amplitude with pulse energy and repetition rate.
Over the past years, ultrafast lasers with average powers in the 100 W range have become a mature technology, with a multitude of applications in science and technology. Nonlinear temporal compression of these lasers to few- or even single-cycle dura

We present a pump-probe technique for monitoring ultrafast polarizability changes. In particular, we use it to measure the plasma density created at the temporal focus of a self-compressing higher-order pump soliton in gas-filled hollow-core photonic

We formulate a generic concept of engineering optical modes and mechanical resonances in a pair of optically-coupled light-guiding membranes for achieving cascaded light scattering to multiple Stokes and anti-Stokes orders. By utilizing the light pre
