“…Moreover, molecular deflection by non-resonant optical dipole force is considered as a promising route to separation of molecular mixtures (for a recent review, see [24]). Narrowing the distribution of the scattering angles may substantially increase the efficiency of separation of multi-component beams, especially when the prealignment is applied selectively to certain molecular species, such as isotopes [25], or nuclear spin isomers [26,27]. More complicated techniques for pre-shaping the molecular angular distribution may be considered, such as confining molecular rotation to a certain plane by using the "optical molecular centrifuge" approach [28], double-pulse ignited "molecular propeller" [29][30][31][32][33], or planar alignment by perpendicularly polarized laser pulses [34].…”

We consider deflection of polarizable molecules by inhomogeneous optical fields, and analyze the role of molecular orientation and rotation in the scattering process. It is shown that molecular rotation induces spectacular rainbow-like features in the distribution of the scattering angle. Moreover, by preshaping molecular angular distribution with the help of short and strong femtosecond laser pulses, one may efficiently control the scattering process, manipulate the average deflection angle and its distribution, and reduce substantially the angular dispersion of the deflected molecules. We provide quantum and classical treatment of the deflection process. The effects of strong deflecting field on the scattering of rotating molecules are considered by the means of the adiabatic invariants formalism. This new control scheme opens new ways for many applications involving molecular focusing, guiding and trapping by optical and static fields.

We control the wave packet evolution with relatively weak laser pulses at fractional revivals which modify the phase between wave packet components. We demonstrate two phase control effects in oxygen: coherently switching revivals off and on, and doubling the revival frequency. When viewed as a quantum logic system, these effects correspond to a Hadamard and a T operation.

“…One can ponder controlling the rotation itself by the (non)resonant alignment or Raman induced polarization spectroscopy methods, where time evolution is detected nonintrusively by the optical Kerr effect. 33,34 For the nonresonant techniques, one is more flexible regarding the molecular level structure as the rotational wave packet is generated on the ground state. N 2 , for example, is a thoroughly investigated molecule with respect to alignment dynamics.…”

states. Due to the large energy separation of vibrational states, the wave packets are superpositions of rotational states only. This allows for a specially detailed inspection of the secondand third-order coherences by a two-dimensional imaging approach. We present the time-frequency domain images to illustrate the intra-and intermolecular interferences, and discuss the procedure to rationally control and experimentally detect the interferograms in solid Xe environment.
