From: Contrasting levels of absorption of intense femtosecond laser pulses by solids
Results from PIC simulation.
(a) Intensity dependent fractional absorption of simulated ‘p’ polarized pulse compared with the experiment. The inset shows the sketch plasma density profile, modelled as two scale lengths (Llow and Lhigh), used in the PIC simulation. (b) Simulated angular distribution of fast electrons (E > 100 keV). The red arrow and black slab indicates laser direction and target orientation, respectively. (c) Simulated intensity dependent spectral shift of the second and third harmonic emission.
