Abstract:
Two-dimensional numerical calculations were made in a study of heat-conduction and hydrodynamic equalisation of the asymmetry of heating and compression of 'laser greenhouse' targets. It is shown that small-scale perturbations become equalised by the high thermal conductivity and by transverse shock waves in the absorber component of a target. It is proposed to use working targets with a surface relief for compensating the strong heating asymmetry associated with coupling of laser radiation through apertures in an outer chamber.
