Title: Energetic electrons driven in the polarization direction of an intense laser beam incident normal to a solid target

Abstract

Experiments were performed at the LLNL Titan laser to measure the propagation direction of the energetic electrons that were generated during the interaction of the polarized laser beam with solid targets in the case of normal incidence. The energetic electrons propagated through vacuum to spectator metal wires in the polarization direction and in the perpendicular direction, and the K shell spectra from the different wire materials were recorded as functions of the distance from the laser focal spot. It was found that the fluence of the energetic electrons driven into the spectator wires in the polarization direction compared to the perpendicular direction was larger and increased with the distance from the focal spot. Finally, this indicates that energetic electrons are preferentially driven in the direction of the intense oscillating electric field of the incident laser beam in agreement with the multiphoton inverse Bremsstrahlung absorption process.

Energetic electron propagation in solid targets driven by the intense electric fields of femtosecond laser pulses

Journal Article Seely, J F ; Szabo, C I ; Audebert, P ; ... - Physics of Plasmas

An analytical model is used to interpret experimental data on the propagation of energetic electrons perpendicular to and parallel to the propagation direction of intense femtosecond laser pulses that are incident on solid targets. The pulses with {approx_equal}10{sup 20} W/cm{sup 2} intensity are incident normal onto a gadolinium or tungsten wire embedded in an aluminum substrate, and MeV electrons generated in the focal spot propagate along the laser direction into the irradiated wire. Electrons also propagate laterally from the focal spot through the aluminum substrate and into a dysprosium or hafnium spectator wire at a distance up to 1 mmmore »« less

Properties of laser-produced GaAs plasmas measured from highly resolved X-ray line shapes and ratios

Journal Article Seely, J. F. ; Fein, J. ; Manuel, M. ; ... - High Energy Density Physics

The properties of hot, dense plasmas generated by the irradiation of GaAs targets by the Titan laser at Lawrence Livermore National Laboratory were determined by the analysis of high resolution K shell spectra in the 9 keV to 11 keV range. The laser parameters, such as relatively long pulse duration and large focal spot, were chosen to produce a steady-state plasma with minimal edge gradients, and the time-integrated spectra were compared to non-LTE steady state spectrum simulations using the FLYCHK and NOMAD codes. The bulk plasma streaming velocity was measured from the energy shifts of the Ga He-like transitions andmore »« less

Lateral propagation of MeV electrons generated by femtosecond laser irradiation

Journal Article Seely, J F ; Szabo, C I ; Audebert, P ; ... - Physics of Plasmas

The propagation of MeV electrons generated by intense (approx =10{sup 20} W/cm{sup 2}) femtosecond laser irradiation, in the lateral direction perpendicular to the incident laser beam, was studied using targets consisting of irradiated metal wires and neighboring spectator wires embedded in electrically conductive (aluminum) or resistive (Teflon) substrates. The K shell spectra in the energy range 40-60 keV from wires of Gd, Dy, Hf, and W were recorded by a transmission crystal spectrometer. The spectra were produced by 1s electron ionization in the irradiated wire and by energetic electron propagation through the substrate material to the spectator wire of amore »« less

Measurements of the energy spectrum of electrons emanating from solid materials irradiated by a picosecond laser

Journal Article Di Stefano, C. A. ; Kuranz, C. C. ; Seely, J. F. ; ... - Physics of Plasmas

Here, we present the results of experiments observing the properties of the electron stream generated laterally when a laser irradiates a metal. We also found that the directionality of the electrons is dependent upon their energies, with the higher-energy tail of the spectrum ( 1MeV and higher) being more narrowly focused. This behavior is likely due to the coupling of the electrons to the electric field of the laser. We performed these experiments by using the Titan laser to irradiate a metal wire, creating the electron stream of interest. These electrons propagate to nearby spectator wires of differing metals, causingmore »« less

Multi-electron beam generation using co-propagating, parallel laser beams

Journal Article Elle, J. ; Zhao, T. Z. ; Ma, Y. ; ... - New Journal of Physics

High intensity short pulse laser plasma interaction experiments were performed to investigate laser wakefield acceleration (LWFA) in the 'bubble' regime. Using a specially designed phase plate, two high intensity laser focal spots were generated adjacent to each other with a transverse spacing of 70 μm and were focused onto a low density plasma target. We found that this configuration generated two simultaneous relativistic electron beams from LWFA (with low divergence) and that these beams often interact strongly with each other for longer propagation distances in the plasma thus reducing beam quality. In addition, it was observed that the existence ofmore »« less
