We propose a novel mechanism of energy absorption in dielectric materials with ultrashort infrared laser pulses of intensities below the damage threshold. Analytical theory, generalized to hole-assisted processes in arbitrarily polarized laser fields, is validated using one-dimensional numerical simulations of the time-dependent Schrodinger equation. Large enhancements in the multiphoton transition rates are found both numerically and analytically. The one-dimensional calculations are extended to two dimensions via a forest. re percolation model, in which nanoplasma-like structures have been identified.

We describe the interaction of ultrashort infrared laser pulses with clusters and dielectrics. Rapid ionization occurs on a sub-laser wavelength scale below the conventional breakdown threshold. It starts with the formation of nano-droplets of plasma which grow like forest fires, without any need for heating of the electrons promoted to the conduction band. The dimensionality of the damaged area can be fractal and changes during the laser pulse. This mechanism is operative in both rare gas clusters and dielectrics interacting with ultrashort, moderately intense laser pulses which include only several periods of the driving field, so that the traditional avalanche mechanisms have no time to develop.
