The analytical model of interaction of a
subpicosecond laser pulse with ultrathin films is offered. With the help
of the given model, the optimization of a carbon Ly-á line emission
falling in the range of "water window" — 3.38 nm is considered. The analysis
of optimum conditions for line emission at film-laser interaction is given.
The results of calculations using the model are in agreement with those
of numerical simulations and the available experimental data.
