Role of the plasma scale length in the harmonic generation from solid targets
Physical Review E - Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics 58:5 (1998) R5253-R5256
Abstract:
We have investigated the generation of high harmonics from the interaction of 150 fsec, 790 nm, and 395 nm laser pulses with solid targets. Experiments are presented that demonstrate a strong dependence of the conversion efficiency on the temporal pulse shape and the resulting density scale length [Formula Presented] of the preformed plasma. The highest conversion efficiencies are achieved for short density scale lengths [Formula Presented] which result from high contrast ratio pulse interactions. © 1998 The American Physical Society.Well characterized 1019W cm2 operation of VULCAN—an ultra-high power Nd:glass laser

Abstract:
Peak intensities of 1019 W cm2 have been reliably obtained from a high power Nd:glass laser using chirped pulse amplification. An Additive Pulse Modelocked oscillator incorporating diode pumped Nd:LMA was used to generate the sub-picosecond pulse. The focal spot intensity distribution has been characterized in detail showing a three times diffraction limited beam. © 1998 Taylor & Francis Group, LLC.Feasibility study of high harmonic generation from short wavelength lasers interacting with solid targets
