    Abstract:
    The application of frequency-swept picosecond laser pulses in achieving efficient population transfer via adiabatic rapid passage (ARP) was described. The basic theoretical considerations useful for understanding ARP in both few-level and multi-level systems were presented. A detailed report of the experimental arrangement and methods used to generate frequency-swept laser pulses was also provided. The results of coherent population transfer experiments on solid phase and vapor phase systems were presented and compared to theoretical calculations on model systems. It was determined that the frequency sweep of the laser pulse need not necessarily be linear, nor even monotonic. Selective excitation and enhanced population will surely occur provided the conditions for ARP are well satisfied.
