“…This EMP contains frequency components up to the GHz and beyond [6,34,68,77]. e) Filamentation also occurs in other media such as transparents liquids or solids [19,23,78,84]. These systems provide a compact model which exhibits a similar physics although at lower energies and on reduced scales.…”

“…While damage is a visible record of the pulse-plasma interaction, it is the initial interaction itself and resulting ultrafast free-electron generation that must be understood and controlled when using femtosecond pulses. * Numerous studies have included a postmortem analysis of the optical damage on the surface and in the bulk and used a wide variety of computer simulations to interpret the results [8,19,[22][23][24][25][26][27]. While those studies have greatly advanced the understanding of the induced-plasma processes and the nonlinear effects inside the material above the damage threshold, physical processes leading up to the damage regime are not accessible with many of these experimental techniques.…”

R. 2012. Interaction of ultrashort-laser pulses with induced undercritical plasmas in fused silica. Phys Rev A, 85(1):013808.PHYSICAL REVIEW A 85, 013808 (2012) Interaction of ultrashort-laser pulses with induced undercritical plasmas in fused silica Ultrafast light-material interactions near the damage threshold are often studied using postmortem analysis of damaged dielectric materials. Corresponding simulations of ultrashort pulse propagation through the material are frequently used to gain additional insight into the processes leading to such damage. However, comparison between such experimental and numerical results is often qualitative, and pulses near to but not exceeding the damage threshold leave no permanent changes in the material for postmortem analysis. In this article, a series of experiments is presented that measures the near-and far-field properties of a 140-fs laser pulse after propagation through a fused silica sample in which a noncritical electron plasma was generated. Concurrently, results from simulations in which the laser pulse was numerically constructed according to the nearfield beam profile and frequency resolved optical gating (FROG) trace are presented. It is found that to extract a quantitative comparison of such data, cylindrical symmetry of the laser pulse in simulations should be abandoned in favor of a fully 3 + 1D Cartesian representation. Further comparison of experimental and calculated damage thresholds shows that time-corrective effects predicted by the Drude model play a critical role in the physics of both pulse evolution and plasma formation. The influence of resulting spatiotemporal dependences of the pulse in far-field measurements leads to unretrievable FROG traces. However, it is shown through both simulation and experiment that the use of an appropriate beam aperture will eliminate this effect when measuring the temporal pulse amplitude.

“…Our approach is based on the self-limiting absorption model for bulk dielectrics that recognizes that nonlinear absorption depletes the beam as it propagates towards the focus [5,14]. It is a unique feature of multiphoton ionization in condensed media that an ultrashort laser pulse will be depleted of photons long before the medium is depleted of unionized atoms.…”

For SiO 2 the threshold change serves as positive feedback reenforcing the process that produced it. This constitutes a memory in nonlinear ionization of the material. The threshold change saturates with the number of pulses incident at a given spot. Irrespective of the pulse energy, the magnitude of the saturated threshold change is constant ( 20%). However, the number of shots required to reach saturation does depend on the pulse energy. Recognition of a memory in ionization is vital to understand multishot optical or electrical breakdown phenomena in dielectrics.
