Stimulated emission pumping and selective excitation by adiabatic passage with frequency-modulated picosecond laser pulses

We demonstrate that picosecond frequency modulated laser pulses produce more efficient population transfer, and more selective excitation than equivalent (same spectral width) nearly transform limited laser pulses. We also note the ″ robustness″, or insensitivity of the properties of the material excitation to the parameters of the laser field, that is inherent to the adiabatic process. The robustness obtainable by adiabatic passage may ultimately prove useful to laboratory applications of theoretical schemes for laser-control of chemical reaction dynamics.
