EXPERIMENTS ON INTENSE LASER IRRADIATION OF PLASMAS

For simulating such a physical tilted beam, a classical paraxial model without accounting for the incidence angle would lead to search a the solution which would be highly

(c) Typical angularly resolved spectrum without laser-plasma lens. The divergence was measured for an electron energy of 270 MeV. The distance between the two stages is L ¼ 2.3 mm.

It is seen on figure 2 that polarization reversal of a domain issued from the nucleation site is practically instanta- neous (in fact photographs with a higher time resolu-

Diffraction of a 633nm laser beam on the monoatomic steps of a vicinal (0001) sapphire surface has been observed, revealing the presence of relatively regular terraces on both

In this paper we discuss and compare these two kinds of boundary conditions again and we present some further results of the numerical calculations of
