Coherent control of wavepacket motion in Cesium dimers

We present an experimental investigation of wave packet dynamics in Cesium dimers. Using femtosecond pump-probe techniques (both degenerate and non-degenerate), we observe transmission oscillations which correspond to motion of the coherent wavepackets in the ground state and in excited states. The use of a second pump beam, the control, allows us to selectively excite certain oscillations and suppress others by adjusting the relative delay between them. Additionally, some preliminary results on Coherent Anti-Stokes Raman Scattering (CARS) in Cesium dimers will be presented.
