Laser and electron deflection from transverse asymmetries in laser-plasma accelerators

Laser-driven plasma-wave electron accelerators

Laser Plasma Accelerators

Particle acceleration by relativistic electron plasma waves generated by intense lasers has been demonstrated in a number of experiments by various mechanisms. Accelerating fields as high as 1 GeV=cm, with electrons accelerated to about 100MeV in millimetre distances have been achieved. These fields produced by intense lasers in plasmas are the largest ever produced in laboratory experiments. T...

Wavefront-sensor-based electron density measurements for laser-plasma accelerators.

Characterization of the electron density in laser produced plasmas is presented using direct wavefront analysis of a probe laser beam. The performance of a laser-driven plasma-wakefield accelerator depends on the plasma wavelength and hence on the electron density. Density measurements using a conventional folded-wave interferometer and using a commercial wavefront sensor are compared for diffe...

Compact x-ray free-electron laser from a laser-plasma accelerator using a transverse-gradient undulator.

Compact laser-plasma accelerators can produce high energy electron beams with low emittance, high peak current but a rather large energy spread. The large energy spread hinders the potential applications for coherent free-electron laser (FEL) radiation generation. We discuss a method to compensate the effects of beam energy spread by introducing a transverse field variation into the FEL undulat...
