Phys. Rev. Lett. 100, 133006 (2008) [4 pages]Rescattering for Extended Atomic SystemsReceived 24 December 2007; published 4 April 2008 Laser-driven rescattering of electrons is the basis of many strong-field phenomena in atoms and molecules. Here, we will show how this mechanism operates in extended atomic systems, giving rise to effective energy absorption. Rescattering from extended systems can also lead to energy loss, which in its extreme form results in nonlinear light-induced trapping. Intense-laser interaction with atomic clusters is discussed as an example. We explain fast electron emission, seen in experimental and numerically obtained spectra, by rescattering of electrons at the highly charged cluster. © 2008 The American Physical Society URL:
