We present an implementation of an additional cost in the functional of the
recently published iteration methods for quantum optimal control [W. Zhu,
J. Botina, and H. Rabitz, J. Chem. Phys. 108, 1953 (1998)] to design optima
l laser pulses for population transfer. The additional criterion takes into
account the asymptotic switch on and off behavior of experimentally genera
ted laser pulses. Exemplarily, a specially adapted windowed Fourier transfo
rm is applied to decompose a complex, highly nonintuitive optimal laser fie
ld in a sequence of subpulses to provide laser pulse parameters as helpful
information for experimental reconstruction. Numerical calculations for thr
ee typical spectroscopic excitation mechanisms show that laser fields obtai
ned with the new functional signify a step towards experimental feasibility
