Autor: S Haessler, V Strelkov, L B Elouga Bom, M Khokhlova, O Gobert, J-F Hergott, F Lepetit, M Perdrix, T Ozaki, P Salières

Publikováno v: New Journal of Physics, Vol 15, Iss 1, p 013051 (2013)

Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this enhancement is still debated. We perform the first temporal characteri

Generation of higher harmonics of femtosecond radiation in clusters

Autor: Tsuneyuki Ozaki, Rashid A. Ganeev, L. B. Elouga Bom

Publikováno v: Optics and Spectroscopy. 108:970-978

The frequency conversion of laser radiation in cluster media is studied by the method of laser ablation of surfaces containing different nanoparticles (Cr2O3, In2O3, Ag, Sn, Au, and Cu). Using plasma that contains In2O3 nanoparticles as an example, i

Evidence of strong contribution from neutral atoms in intense harmonic generation from nanoparticles

Autor: Tsuneyuki Ozaki, L. B. Elouga Bom, J. Abdul-Hadi, Rashid A. Ganeev

Publikováno v: Laser and Particle Beams. 28:69-74

We show experimental evidence that, for the intense high-order harmonics from nanoparticles, there is a strong contribution from neutral atoms. We present the results of studies on the harmonics generated in laser-produced plasmas containing various

Publikováno v: Applied Physics B. 96:491-498

We analyze the morphology of ablated nanoparticles after their laser-induced deposition on various substrates. We show that, at moderate laser intensity of the 210 ps pulses on the surface of nanoparticle-containing materials (

Extending the capabilities of ablation harmonics to shorter wavelengths and higher intensity

Autor: L. B. Elouga Bom, Tsuneyuki Ozaki, Rashid A. Ganeev

Publikováno v: Laser and Particle Beams. 26:235-240

We study the generation of high-order harmonics from plasma plume, by using the 20 TW, 10 Hz laser of the Advanced Laser Light Source (ALLS). We perform detailed studies on enhancement of single high-order harmonics generated in laser plasma using th

Higher harmonic generation in laser plasma upon interaction of femtosecond laser pulses with doubly and singly charged ions under conditions of resonance frequency conversion of laser radiation

Autor: Tsuneyuki Ozaki, Rashid A. Ganeev, L. B. Elouga Bom

Publikováno v: Optics and Spectroscopy. 104:258-268

The higher harmonic generation (HHG) in plasmas formed on the surface of different solid targets (Pb, Ag, Ge, In, Au, Cr, Pt, V, Mn, Ga, Bi, Sb, Cu, Al, Ca, and Sn) by laser ablation is studied. The possibility of HHG upon interaction of femtosecond

Publikováno v: Laser and Particle Beams. 25:321-325

We perform systematic investigation of a new method for generating high-order harmonics, using ablation as the nonlinear medium. We place emphasis on clarifying the pump laser conditions for optimum harmonic yield. For this purpose, we use the Ti:Sap

Blueprint for generating intense attosecond pulses using high-order harmonics from graphitic carbon plasma

Autor: Y. Pertot, L. B. Elouga Bom, J. Abdul-Hadi, Tsuneyuki Ozaki

Publikováno v: 2010 IEEE Photinic Society's 23rd Annual Meeting.

We report the generation of extremely efficient (> 10−4), multi -µJ high -order harmonics from graphitic carbon plasma, which spans over five harmonic orders. This broad bandwidth is ideal for generating intense single-cycle attosecond pulses.
