The efficiency of the laser energy conversion to a shock wave has been investigated in solid targets irradiated by a single or two consecutive laser beams. The first laser pulse was used to produce the plasma simulating conditions relevant to shock ignition approach. One and two-layer planar targets were irradaited using first and third laser harmonics with wavelengths of 1.315 and 0.438 μm, respectively. Three-frame interferometry and measurements of crater parameters were used as the main diagnostics. The contribution of fast electrons to ablation and the laser energy conversion into shock wave have been investigated for different conditions of the target irradiation, including the pre-plasma presence. 2D numerical simulations and theoretical analysis were carried out to support explanation of experimental results.
