Multiphoton ionisation of He atoms at 532 nm
Summary, in English
Multiphoton ionisation of He at 532 nm is investigated at about 1013 W cm-2 by measuring both electron energy distribution, and the laser intensity dependence of the production of He+ and He2+ ions. He2+ ions solely come from multiphoton ionisation of He+ ions.
