摘要：

Optical methods based on instantaneous measurements of the optical refractive index and of the absorption coefficient allow observation in real time, with a resolution of 10(-13) s, of the evolution of an electron gas injected into the conduction band of a wide-bandgap insulator. In particular, the ultrafast dynamics of charge trapping, excitonic processes and point defect creation can be studied in this way.
