Spectral modification of an intense (>= 10(18) W cm(-2)) laser pulse propagating in a helium gas target was studied using Thomson scattering diagnostic. The spectra recorded at 90 degrees to the laser propagation and polarization direction show a significant modulation and modification of the incident laser pulse during its interaction and propagation through the helium gas target. Simulations suggest that such a modulation in the spectrum of the laser pulse could arise due to its interaction with the self excited plasma waves. (C) 2012 Elsevier B.V.

Abstract
Spectral modification of an intense (>= 10(18) W cm(-2)) laser pulse propagating in a helium gas target was studied using Thomson scattering diagnostic. The spectra recorded at 90 degrees to the laser propagation and polarization direction show a significant modulation and modification of the incident laser pulse during its interaction and propagation through the helium gas target. Simulations suggest that such a modulation in the spectrum of the laser pulse could arise due to its interaction with the self excited plasma waves. (C) 2012 Elsevier B.V.File in questo prodotto:
