Coherent Preparation of Molecular Hydrogen in (v, J, M) Eigenstates for Reaction Dynamics Studies
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 (v=0, 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 (v=1, J=2) 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.
