Abstract:

We have proposed and demonstrated a robust coherent optical technique, the Stark induced adiabatic Raman passage or SARP for preparing single vibrational energy eigenstate of a molecule. Using SARP we have, for the first time, demonstrated population inversion between a ground vibrational v0, J and an excited v 0, J vibrational level of H2 within the ground X 1Sigma g electronic state. In addition, we have prepared a coherent superposition of degenerate M-states belonging to a single rovibrational v1, J2 energy eigenstate within the ground X 1Sigma g electronic state of H2. The phase entangled superposition states opened new avenues to coherently control the collision dynamics, which may also allow us to measure the geometrical phase effect in a collision process. SARP provides a unique way to prepare high lying vibrational energy eigenstate using commercially available nanosecond pump and Stokes pulses.
