From: Ultrafast evolution of electric fields from high-intensity laser-matter interactions
Particle-In-Cell simulations. (a) Electric field E T radiated 115 fs and 175 fs after the interaction with the laser. The intensity is plotted in terms of the laser strength parameter a0. The transverse size of the field emitter grows as the unbalanced charge spreads on target. (b) Side view for the field emitted at 350 fs. The geometry of the simulated wedged target is also shown. (c) Extrapolated field. The fit at distance z is calculated according to the power law E T (z) = a ⋅ zb, with b = − 1.9 ± 0.2. (d) Simulated EOS snapshot as detected by the CCD. The radiation in (a,b) is propagated toward and through the EOS crystal, where it is sampled by the probe laser.
