A selective excitation of closely spaced Raman transitions using femtosecond pulse shaping is studied within a semiclassical approach. An analytical pulse function is proposed having duration T that selectively excites one of two transitions separated by a frequency interval less than 1/ T . It is shown that, for intense fields, both the field amplitude and pulse frequency spectrum have to be carefully chosen to achieve the control of excitations. © 2004 Wiley Periodicals, Inc.
