Laser-driven plasma-based accelerators, which are capable of supporting fields in excess of
100 GV∕ m, are reviewed. This includes the laser wakefield accelerator, the plasma beat …

We demonstrate a significant extension of the high-order harmonic cutoff by using a fully-
ionized capillary discharge plasma as the generation medium. The preionized plasma …

A method of creating plasma channels with controllable depth and transverse profile for the
guiding of short, high power laser pulses for efficient electron acceleration is proposed. The …

The propagation of an ultrashort and relativistically intense laser pulse in a preformed
plasma channel is investigated. The nonlinear paraxial wave equation describing the laser …

We demonstrate intense pulse guiding in efficient femtosecond end-pumped waveguides
generated in clustered gases. This novel scheme provides a route to significantly lower on …

We demonstrate the efficient generation of plasma waveguides in elongated cluster gas jets
using 100 ps axicon-generated Bessel beam pump pulses. The plasma waveguide space …

Analytic solutions are presented to the non-paraxial wave equation describing an ultra-short,
low-power, laser pulse propagating in a plasma channel. Expressions for the laser pulse …

We report the use of a preionized medium created by a capillary discharge to extend the
cutoff photon energy in high-order harmonic generation. The observed enhancements result …

Clustered gas jets are shown to be an efficient means for plasma waveguide generation, for
both femtosecond and picosecond generation pulses. These waveguides enable …

We report the generation of dense plasma waveguides containing a large concentration of
silver ions by means of a fast (∼ 55 ns first half-cycle) microcapillary discharge. Concave …
