Interaction of superintense femtosecond laser pulses with freely suspended thin films

Abstract

In this paper some advantages of using thin freely suspended films as a target in femtosecond laser-plasma interaction are discussed. It is shown by numerical simulation for carbon film, that for 10 - 30 nm films significant increase in plasma temperature can be achieved due to strongly limited thermoflux deep into the target. This increase in temperature is accompanied by increase in x-ray yield. The other task of this work is to investigate whether it is possible to excite surface plasmon-polariton for the thin film target.
