Coherent transients as a highly sensitive probe for femtosecond pulse shapers (2004)
Wohlleben,Wendel, Degert,J., Monmayrant,A., Chatel,B., Motzkus,Marcus, Girard,B.
Adiabatic excitation of rotational ladder by chirped laser pulses (2004)
We discuss rotational excitation of molecules by a pair of left and right circularly polarized laser pulses. The pulses are supposed to be short enough to avoid relaxation (femto- or picosecond),...

Zamith, S., Blanchet, V., Girard, B., Andersson, J., Sorensen, S. L., Hjelte, I., ...
We study the dynamics of highly excited states in acetylene initiated by an ultrashort vacuum ultraviolet laser pulse. Electronic states lying in the 4s-3d Rydberg region are excited with one...

(3 + 1)-resonance enhanced multiphoton ionization-photoelectron spectroscopy (REMPI-PES) has been carried out via various low vibrational levels of the D, F, and E states belonging to the (3d-4s)...
Interferences of Ultrashort Free Electron Wave Packets (2002)
Wollenhaupt, M., Assion, A., Liese, D., Sarpe-Tudoran, Ch., Baumert, T., Zamith, S., ...
Interferences of free electron wave packets generated by a pair of identical, time-delayed, femtosecond laser pulses which ionize excited atomic potassium have been observed. Two different schemes...
Zamith, S., Degert, J., Stock, S., De Beauvoir, B., Blanchet, V., Bouchene, M. A., ...
The effects of coherent excitation of a two-level system with a linearly chirped pulse are studied theoretically and experimentally [in Rb ( 5s-5p)] in the low field regime. The coherent transients...
Bouchene, M. A., Zamith, S., Girard, B.
This paper presents a theoretical analysis of the possibilities of producing spin-polarized electrons with a sequence of two ultra-short time-delayed laser pulses. The first pulse, which is right...
Sokell, E., Zamith, S., Bouchene, M. A., Girard, B.
The precession of orbital and spin angular momentum vectors has been observed in a pump-probe study of the 4P fine-structure states of atomic potassium. A femtosecond pump pulse prepared a coherent...
Nicole, C., Bouchene, M. A., Zamith, S., Melikechi, N., Girard, B.
A sequence of two identical ultrashort laser pulses creates quantum interferences in an atom. In the weak-field regime, the observed beats between interferences arising from various transitions are...
Hyperfine structure measurements in the IF B-X system (1992)
Gouédard, G., Billy, N., Girard, B., Vigué, J.
We have measured and analyzed the hyperfine structure of a large number of optical transitions belonging to the IF B-X system. These transitions sample a large range of rovibrational levels ($9 \leq...
