Reaction Dynamics Using a Coherent M-state Superposition Within a Single (v, J) Rovibrational Energy Eigenstate
Abstract
We are reporting our progress and our ongoing effort in preparing quantum states of H2 molecules using Stark induced adiabatic Raman passage (SARP). The supplement award (Grant # W911NF1510192), made it possible to acquire the necessary small cap equipment including, a high voltage power supply, a dry scroll pump, a X-Y-Z vacuum manipulator, a high fidelity pulsed valve, a chiller (refrigerator) for cooling dyes and a few necessary optics, for example lens, half-wave retarder, high power dielectric mirrors and high power UV polarizers. These components were absolutely necessary for extending SARP in preparing new quantum states that can be potentially applied to study low energy collisions. Using SARP with a sequence of delayed pump and Stokes pulses we have not only been able to generate H2 (v=1, J=0,1,2,3) states with a significant population of the ground vibrational (v=0) state, recently we have been successful in pumping a HD molecule from the ground (v=0) to HD (v=4) state with a significant population of the initial ground HD (v=0) state. This high vibrational pumping using SARP is a major break-through, which opens many possibilities for coherently driven chemistry and ultracold chemistry.
