Frequency modulated picosecond laser pulses are applied to the X→B electronic transition in I2 vapor. In the adiabatic limit, these pulses generate more excitation in I2 vapor than do ‘‘transform-limited’’ laser pulses. Multilevel effects make it important to match the pulse bandwidth to the material absorption spectrum, as demonstrated experimentally.

    The quasicontinuum of the vibrationally hot (∼10 CO2 laser photons) C2F5Cl molecule was investigated using a two-laser pulse arrangement. The first laser pulse preheated the molecules into the QC (quasicontinuum) while the second picosecond CO2 laser was employed to probe the absorption...

    In molecular electronic transitions, a vertical transition can be induced by an ultrashort laser pulse. That is, a replica of the initial nuclear state -- times the transition dipole moment of the electronic transition -- can be created instantaneously (on the time scale of nuclear motion) in...

    A method is described whereby photoelectrons generated by a short laser pulse at the cathode of a parallel-plate electrode arrangement are depleted by attachment to C6F6 molecules mixed with N2 in the interelectrode space as they drift to the anode under an externally applied electric field. The...

    Recent theoretical studies suggest the feasibility of laboratory adaptive feedback optimal control (AFOC) of chemical processes with the use of ultrashort laser pulses. The feedback process is introduced to provide robustness to laboratory error and electric field design uncertainties. Adaptive...

    Recent experimental and computational studies on intense short-pulse-laser interactions with small objects such as molecules (C[sub 60]) and clusters are reviewed. An anisotropic Coulomb explosion of C[sub 60] was observed, on irradiation by a high-intensity laser pulse (1 × 10[sup...

    We show that molecules with a moderate permanent dipole moment can be oriented with combined electrostatic and pulsed, nonresonant laser fields. Carbonyl sulfide (OCS) molecules are used as a sample. The degree of orientation can be increased by increasing the peak intensity of the laser field...
