A possibility of input of high-power laser pulse into a
cavity through a hole was studied by means of 2D numerical
calculations. Such tasks appear in view of investigation
of the effective targets with internal input of energy
(Bessarab et al. 1992; Basov et al. 1998),
“cannon-ball” (Hogan 1989), “Greenhouse”
targets (Gus'kov et al. 1995).
We have used two Euler codes “NUTCY” and “FAKEL”
to model the problems of laser beam input into a cavity
through the holes.
