Density n e (x) of a plasma with collisions exceeding the cut-off density with an incident purely penetrating laser beam (hv) which can also be constructed in this case by the WKB approximation. The variation of the quantity E y 2 + H z 2 results in the nonlinear forces f NL.

Generation of blocks of deuterium plasma moving with velocities above 10 9 cm/s against the neodymium glass laser light (positive velocities v to the right) and moving into the plasma interior (negative velocities) at irradiation by a neodymium glass laser of W/cm 2 intensity onto an initially 100eV and 100µm thick bi-Rayleigh profile with minimum internal reflection.

Scheme of skin depth laser interaction where the non-linear force accelerates a plasma block against the laser light and another block towards the target interior. In front of the blocks are electron clouds of the thickness of the effective Debye lengths of less than 500 nm.
