“…The idea of using lasers to accelerate particles was first proposed by Shimoda [21] and others in the 1960's, while lasers themselves were still in their infancy. It was not until much later that the first experiments demonstrating acceleration of electrons with light appeared.…”

Optical microbunches with a spacing of 800 nm have been produced for laser acceleration research. The microbunches are produced using a inverse Free-ElectronLaser (IFEL) followed by a dispersive chicane. The microbunched electron beam is characterized by coherent optical transition radiation (COTR) with good agreement to the analytic theory for bunch formation. In a second experiment the bunches are accelerated in a second stage to achieve for the first time direct net acceleration of electrons traveling in a vacuum with visible light.This dissertation presents the theory of microbunch formation and characterization of the microbunches. It also presents the design of the experimental hardware from magnetostatic and particle tracking simulations, to fabrication and measurement of the undulator and chicane magnets. Finally, the dissertation discusses three experiments aimed at demonstrating the IFEL interaction, microbunch production, and the net acceleration of the microbunched beam.At the close of the dissertation, a separate but related research effort on the tight focusing of electrons for coupling into optical scale, Photonic Bandgap, structures is presented. This includes the design and fabrication of a strong focusing permanent magnet quadrupole triplet and an outline of an initial experiment using the triplet to observe wakefields generated by an electron beam passing through an optical scale accelerator. Beyond the immediate influences on my career of those at SLAC and Stanford,

“…Here, we mainly concentrate on Potassium Dihydrogen Phosphate (KDP), a negative uniaxial crystal commonly used for frequency multiplication of Nd:YAG lasers 3 . In this case, phase matching can be achieved for parallel beams 2 We do not intend this technique as a route for Fast Ignition since the spectrum of the ions is too energetic once the RPD regime is operational. 3 In the rest of the paper we assume for KDP the following Sellmeier's equations: ("collinear geometry") when the pump beam is at an angle θ m with respect to the KDP optical axis:…”

The existence of efficient ion acceleration regimes in collective laser-plasma interactions opens up the possibility to develop high-energy physics facilities in conjunction with projects for inertial confinement nuclear fusion (ICF) and neutron spallation sources. In this paper, we show that the pulse compression requests to make operative these acceleration mechanisms do not fall in contradiction with current technologies for high repetition rate ICF drivers. In particular, we discuss explicitly a solution that exploits optical parametric chirped pulse amplification and the intrinsic modularity of the lasers aimed at ICF.

“…Although the potential of lasers for particle acceleration was yet recognized in the early 1960's [1], research over the past 50 years has shown that developing an effective laser acceleration scheme is not straightforward. In the explosion-like interaction of tightly focused ultra-intense laser pulses with matter, electrons are violently expelled out of the focal region and are effectively accelerated only over short distances, typically comparable to the dominant wavelength of the pulse spectrum.…”

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 23-keV electron beam produced by a radially polarized laser pulse tightly focused into a low density gas. Theoretical analyses suggest that the production of collimated attosecond electron pulses is within reach of the actual technology. Such an ultrashort electron pulse source would be a unique tool for fundamental and applied research. In this paper, we propose an overview of this emerging topic and expose some of the challenges to meet in the future.
