Abstract

The construction of powerful multi-beam Nd-laser facilities with pulse energy of 1-2 MJ for the demonstration of 'ignition' in thermonuclear targets is in progress in USA and France. The projects of such facility are also developed in Russia. Such facility is supposed to be built for a few stages. At the intermediate stage it will operate only with a few beams and high symmetry of the spherical target irradiation might not be obtained. The report present the results of 2D beam powerful Nd-laser with energy 100 kJ and pulse duration of 3 ns. On the basis of our simulation we obtained that in case of appropriate profile of laser irradiation of the targets with adjusted thickness relief one can get relatively high neutron yield at the given laser energy.
