Using intense mode-locked CO2 laser pulse trains we verified the occurrence of the laser-induced, new-type dynamic optical tunneling of electrons from a gold surface. The results are in accordance with the theoretical predictions and our previous experiments carried out for both atoms and gold surface using single longer (ns) CO2 laser pulses. Unknown properties of the development of the CO2 laser train are revealed based on our higher-order coherence detection of electron emission.

Up to Xe3+ were detected and all the multiple ionizations could be explained by tunneling (to be published)Google Scholar
