Abstract
Ultrashort high intensity pulse creates extreme non-equilibrium condition in bandgap material producing dramatic perturbations in electronic structure that, in its turn, leading to changes in electronic, magnetic, and optical states of condensed matter. Interesting experimental results have recently been reported on transient phenomena ranging from ultrafast laser induced detection denial to light induced high temperature superconductivity. While single pulse interaction with bandgap material is well observed, explained and documented, one of the major problem is to maintain meta-stability of such matter states: stability of transient effects that may last well beyond thermalization time. The objective of this paper is to discuss approaches to meta-stability of transient states.
