Electron Acceleration by a Radially Polarized Laser Pulse in an Azimuthal Magnetic Field

Direct Electron Acceleration with Radially Polarized Laser Beams

In the past years, there has been a growing interest in innovative applications of radially polarized laser beams. Among them, the particular field of laser-driven electron acceleration has received much attention. Recent developments in high-power infrared laser sources at the INRS Advanced Laser Light Source (Varennes, Qc, Canada) allowed the experimental observation of a quasi-monoenergetic ...

Electron acceleration by a laser pulse in a plasma.

132 LLE Review, Volume 67 The motion of a charged particle in an electromagnetic field is a well-known paradigm of physics.1,2 Suppose that the field is associated with a laser pulse of finite extent propagating in a vacuum. As the pulse overtakes the particle, the particle gains energy and momentum at the expense of the pulse. At the peak of an intense pulse, the particle has considerable (lon...

Electron acceleration by a self-diverging intense laser pulse.

Electron acceleration by a laser pulse having a Gaussian radial and temporal profile of intensity has been studied. The interaction region is vacuum followed by a gas. The starting point of the gas region has been chosen around the point at which the peak of the pulse interacts with the electron. The tunnel ionization of the gas causes a defocusing of the laser pulse and the electron experience...

Spontaneous emergence of non-planar electron orbits during direct laser acceleration by a linearly polarized laser pulse

Numerical Simulation of an Intense Isolated Attosecond Pulse by a Chirped Two-Color Laser Field

We investigate theoretically the high-order harmonic spectrum extension and numerical generation of an intense isolated attosecond pulse from He+ ion irradiated by a two-color laser field. Our simulation results show that the chirp of the fundamental field can control HHG cutoff position. Also, these results show that the envelope forms of two fields are important factors for controlling the re...
