Abstract
Sodium atoms are ionized by 777 nm, 150 fs laser pulses. Modulations are observed in the multiphoton ionization yield as a function of laser intensity. The oscillations are attributed to Ramsey interference caused by coherent population transfer between bound states at two different times during a single laser pulse.Keywords
