A possible mechanism of arising of strong induced absorption in transparent dielectrics under the action of a high-power short light pulse is discussed. A simple qualitative analysis has been carried out under the assumption that the absorption in the transparent medium arises due to the excitation of electrons to the conduction band by the resonant tunnel transitions between the real energy levels arising in the system under the intensive light action.

Keywords: tunnelling, light action, optical breakdown, resonant transitions
PACS: 81.07.-b, 81.16.-c
