Results are presented from the two-dimensional numerical simulations of las
er energy input into a hohlraum through a hole. This problem is of interest
for ICF research, specifically, for optimization of laser microtarget desi
gn. The optimum relations are found between the hole size and the effective
laser spot radius under conditions close to those of present-day ICF exper
iments. (C) 2000 MAIK "Nauka/Interperiodica".
