Abstract

Direct ionization of hydrogen atoms by laser irradiation is investigated as a potential new scheme to generate proton beams without stripping foils. The time-dependent Schrödinger equation describing the atom-radiation interaction is numerically solved obtaining accurate ionization cross-sections for a broad range of laser wavelengths, durations and energies. Parameters are identified where the Doppler frequency up-shift of radiation colliding with relativistic particles can lead to efficient ionization over large volumes and broad bandwidths using currently available lasers.

High-field electron-photon interactions

Conference Hartemann, F V

Recent advances in novel technologies (including chirped-pulse amplification, femtosecond laser systems operating in the TW-PW range, high-gradient rf photoinjectors, and synchronized relativistic electron bunches with subpicosecond durations and THz bandwidths) allow experimentalists to study the interaction of relativistic electrons with ultrahigh-intensity photon fields. Ponderomotive scattering can accelerate these electrons with extremely high gradients in a three-dimensional vacuum laser focus. The nonlinear Doppler shift induced by relativistic radiation pressure in Compton backscattering is shown to yield complex nonlinear spectra which can be modified by using temporal laser pulse shaping techniques. Colliding laser pulses, where ponderomotive acceleration and Compton backscattering are combined,more »« less

High-intensity scattering processes of relativistic electrons in vacuum

Journal Article Hartemann, F V ; Department of Applied Science, University of California, Davis, California95616 - Physics of Plasmas

Recent advances in novel technologies such as chirped pulse amplification and high gradient rf photoinjectors make it possible to study experimentally the interaction of relativistic electrons with ultrahigh intensity photon fields. Femtosecond laser systems operating in the TW{endash}PW range are now available, as well as synchronized relativistic electron bunches with subpicosecond durations and THz bandwidths. Ponderomotive scattering can accelerate these electrons with extremely high gradients in a three-dimensional vacuum laser focus.

Analytical description of generation of the residual current density in the plasma produced by a few-cycle laser pulse

Journal Article Silaev, A. A., E-mail: silaev@appl.sci-nnov.ru ; Vvedenskii, N. V., E-mail: vved@appl.sci-nnov.ru ; University of Nizhny Novgorod, Nizhny Novgorod 603950 - Physics of Plasmas

When a gas is ionized by a few-cycle laser pulse, some residual current density (RCD) of free electrons remains in the produced plasma after the passage of the laser pulse. This quasi-dc RCD is an initial impetus to plasma polarization and excitation of the plasma oscillations which can radiate terahertz (THz) waves. In this work, the analytical model for calculation of RCD excited by a few-cycle laser pulse is developed for the first time. The dependences of the RCD on the carrier-envelope phase (CEP), wavelength, duration, and intensity of the laser pulse are derived. It is shown that maximum RCDmore »« less

An optical technique for measuring divergence, beam profile, and aiming direction, of relativistic negative hydrogen ions

Conference Hershcovitch, A

A novel, nonobstructive diagnostic technique for high energy H/sup minus/D/sup minus/ ion beams is described. This scheme employs spectroscopic techniques designed to measure beam profile, perpendicular velocity spread (i.e., divergence), and orientation of multiMeV H/sup minus/ beams. The basic principle of this method is to photoneutralize a small portion of the H/sup minus/ beam in a way such that the photodetachment process results in the formation of excited hydrogen atoms in the n = 2 levels. Observation of fluorescence from spontaneous decay of H(sp) andor induced deacy of H(2s) can be readily used to determine beam profile. Doppler broadening measurementsmore »« less

Resonant four-photon ionization of atomic hydrogen

Journal Article Kelleher, D E ; Ligare, M ; Brewer, L R - Phys. Rev. A; (United States)

We have measured the three-photon resonant, four-photon ionization profile of atomic hydrogen. The width of the profile is large compared with the laser bandwidth, fine-structure splitting, Doppler width, and radiative and collisional rates. The shape, shift, width, and laser intensity dependence of the measured profiles are in excellent agreement with theoretical predictions.
