Intense Laser Pulse Guiding in Preformed Plasma Waveguides
نویسنده
چکیده
Preformed plasma waveguides capable of controllably guiding relativistically intense femtosecond laser pulses over multiple Rayleigh lengths without optical distortion are essential to developing GeV-scale laser wakefield accelerators (LWFAs). We present recent experimental results showing guiding of pulses at intensities above 10 W/cm. Pump-probe experiments further characterize guided pulse propagation, and provide tools for characterizing channeled LWFAs. Particle-in-cell simulations of a Raman-seeded channeled LWFA are presented.

One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...
متن کاملGuiding of relativistic laser pulses by preformed plasma channels.
Guiding of relativistically intense (>10(18) W/cm2) laser pulses over more than 10 diffraction lengths has been demonstrated using plasma channels formed by hydrodynamic shock. Pulses up to twice the self-guiding threshold power were guided without aberration by tuning the guide profile. Transmitted spectra and mode images showed the pulse remained in the channel over the entire length. Experim...

The physics of plasma-based accelerators driven by short-pulse lasers is reviewed. This includes the laser wakefield accelerator, the plasma beat wave accelerator, the self-modulated laser wakefield accelerator, and plasma waves driven by multiple laser pulses. The properties of linear and nonlinear plasma waves are discussed, as well as electron acceleration in plasma waves. Methods for inject...

In this paper, we have simulated the excitation of wake fields in the interaction of an intensive laser pulses having Half-Sine and Gaussian time envelopes with a fully ionized cold plasma using particle in cell (PIC) method. We investigated the dependency of wake filed amplitude to different laser and plasma parameters such as laser wavelength, pulse duration and electron number density. In ad...
