Observation of monoenergetic relativistic electron beams from intense laser - plasma interactions
Optics InfoBase Conference Papers (2006)
Abstract:
We report the observation of monoenergetic electron beams (dE/E < 5%) produced by the interaction of a 12TW, 40fs laser pulse with underdense plasma, in contrast to all previous experiments, which produced energy spreads ~100%. 漏 2005 Optical Society of America.Of Proton Generation and Focusing for Fast Ignition Applications

The effect of laser focusing conditions in laser wakefield acceleration experiments
Optics InfoBase Conference Papers (2006)
Abstract:
The effect of focusing conditions in laser wakefield acceleration is studied. Short focal length geometries produce large dark currents while longer focal lengths produce narrow energy spread beams. 漏 2006 Optical Societ of America.A coupled two-step plasma instability in PW laser plasma interactions

Abstract:
A possible new mechanism for anomalous ion heating in ultra-intense laser plasmas is considered here. This mechanism is based on the excitation of an electron two-stream instability that is driven by the fast electron beam and resonantly decays into ion-acoustic waves. These low frequency waves are then strongly damped by the ion collisions in the dense plasma. The model gives a simple explanation for the preferential heating of the bulk ion population observed in recent laser experiments in the petawatt (PW) regime. 漏 2005 IOP Publishing Ltd.Characterization of Ti Ka radiation resulting from interaction of a highly intense laser pulse with a thin titanium foil
