Using the upgraded Vulcan Petawatt laser at 3×1020 Wcm-2 intensities, target interactions and acceleration in a gas jet were studied. Electron spectra with energies up to 240 MeV were detected. Indications of a new acceleration regime, which results in a non-Maxwellian distribution were observed. © 2000 Optical Society of America.

Temporally and spatially resolved measurements of inverse Faraday effect (IFE) in a plasma using a self-channeling laser pulse of relativistic intensity were studied. The magnetic fields so obtained were much larger than expected, and have a duration approaching that of the high intensity laser pulse. The simulation results show that the magnetic field is generated by fast electrons which spiral around the axis of the channel created by the laser field.

Measurements of Raman instabilities with subpicosecond time resolution in the referential frame of the laser pulse were carried out. It was found that Raman 30° side scattering and forward scattering occur at the back of the pulse. A simple model was developed that allows to calculate RFS spectra with a good accuracy.

High-intensity laser-plasma interaction experiments were performed using high-power laser pulses (greater than 8 TW) at a wavelength of 527 nm. These pulses were focused to intensity greater than 1018 W/cm2 into underdense helium plasma at a density of ne < 5 x 1019 cm~3. Systematic examination of the forward Raman scattering instability was performed by measuring the spectrum of the forward scattered light. It was found that the three-wave instability occurs first, which then proceeds to a nonlinear regime involving four-wave processes. Measurements of the accelerated electron spectrum suggest that higher phase velocity plasma waves are generated than when using lower frequency light. l ©2000 IEEE.
