Abstract
Thr results of calculations of the transmission of a laser pulse (of l ength 0.4-1.0 ns) through a hole of diameter 100-500 mu m based on 3 o ne-dimensional hydrodynamics code are compared with experimental data, The model is based on plasma implosion inside a cylindrical cavity. T he hydrodynamic calculations show that the transmission coefficient de pends strongly on the diameter of the laser beam as well as of the hol e and also on the pulse length. A weak dependence of the transmission coefficient on the laser Light intensity is found. The theory agrees w ell with the results of experiments.
