High-order harmonic generation by nonlinear reflection of an intense high-contrast laser pulse on a plasma

Optics Letters (2004)

P. Monot Gilles Doumy Sundrine Dobosz Michel Perdrix P. D’Oliveira

We demonstrate the use of a plasma mirror to obtain 60-fs 10-TW laser pulses with a temporal contrast of 108 on a nanosecond time scale and 106 on a picosecond time scale, and we use these high-contrast pulses to generate high harmonics by nonlinear reflection on a plasma with a steep electronic density gradient. Well-collimated harmonics up to 20th order are observed for a laser intensity of ≈3×1017 W/cm2, whereas no harmonics are obtained without the plasma mirror.

Bessel beam transformation by anisotropic crystals

Journal of the Optical Society of America A (2010)

Dmitriy Zusin Raman Maksimenka Valerii V. Filippov R. V. Chulkov Michel Perdrix

Transformation of Bessel beams by biaxial and uniaxial crystals is investigated experimentally and theoretically. Experimental observations show beam symmetry changing and formation of complex intensity patterns, depending on the orientation of the crystal. These patterns can appear as a regular system of peak intensities. Results of numerical calculations support the experimental findings.

<title>Utilization of a plasma mirror for the production of high-order harmonics from a planar surface</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2004)

P. Martín P. Monot Gilles Doumy S. Dobosz Michel Perdrix

We investigate the harmonics generation from a pure dielectric target when submitted to laser intensities in the 10¹⁸W/cm². We demonstrate the negative influence of the prepulses and ASE by addressing the direct comparison of the harmonic spectra with and without the introduction of a perfectly controlled plasma mirror system. Harmonics up to the 20th of the fundamental of the Ti-Sa laser are clearly visible in a situation free of any plasma expansion.

<title>Correlation between copper photoemission spectra and spectra of x-ray pulses produced by sub-picosecond laser-irradiated noble gas clusters</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2004)

P. Palianov J. Gaudin F. Quéré P. Meynadier Michel Perdrix

Interaction of a cluster jet with a very intense laser pulse generates x-rays in the keV domain. Many features of this type of source are well characterized and understood but their temporal structure is still being discussed. We performed experiments on photoelectron emission of a pure copper metallic sample irradiated by such a source of x-rays. We determined the best laser and gas jet parameters in order to enhance the photoemission yield. The maximum signal was obtained with 30 bars of xenon irradiated by 250 fs 75 mJ pulse at 800 nm, corresponding to an intensity of 2.10¹⁶ W/cm². We were able to observe a peak of Auger electrons at 62 eV in the photoelectron spectrum. This suggests that pulse duration measurements based on the Laser Assisted Auger Decay (LAAD) technique are possible.

<title>Subpicosecond dynamics of intense laser-cluster interaction: keV x rays and highly charged ion production</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2001)

E. Lamour Serge Dreuil Jean-Claude J. Gauthier O. Gobert P. Meynadier

We have performed studies of keV x-ray production from (formula available in paper) rare gas clusters submitted to intense IR laser pulses. Up to (formula available in paper) per pulse at a moderate atomic density have been observed. High resolution spectroscopy studies in the case of (formula available in paper) clusters have also been performed, gibing unambiguous evidence of highly charge ions with K vacancies production. We have determined the photon energies and the absolute photon emission yields as a function of several physical parameters governing the interaction: size and atomic number of the clusters, peak intensity of the laser. Unexpectedly low laser intensity thresholds have been measured. The result obtained indicate nevertheless that x-rays may be emitted before cluster explosion on a subpicosecond time scale, and that several mechanisms must be involved in the first stage of the production of the hot nanoplasma induced from each cluster.

<title>Laser ablation efficiency of pure metals with femtosecond, picosecond, and nanosecond pulses</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (1998)

A. Semerok Catherine Chaleard Vincent Detalle Sylvain Kocon Jean-Luc Lacour

Laser ablation of pure metals by femtosecond, picosecond and nanosecond pulses is studied experimentally in air at atmospheric pressure. Craters created by interaction of visible and UV laser pulses with the targets are investigated. The dependence of the ablation efficiency in terms of ablated volume per unit of energy on the pulse duration and wavelength is discussed.
