Studies of the interaction of molecules and solids with subpicosecond approx. 600 fs high intensity radiation or 10 to the 16th Wsq. cm. are leading to the observation of new physical phenomena and the production of new classes of highly excited matter. The experiments indicate that a central factor is the ability to generate very high levels of electronic excitation in a manner which enables the heavy bodies of the system to remain kinetically cold for the time scale of the interaction.
