Field-free two-direction alignment alternation of linear molecules by elliptic laser pulses
D. Daems, S. Guérin, E. Hertz +3
We show that a linear molecule subjected to a short specific elliptically polarized laser field yields postpulse revivals exhibiting alignment alternatively located along the ortho…
Efficient and long-lived field-free orientation of molecules by a single hybrid short pulse
D. Daems, S. Guérin, D. Sugny +1
We show that a combination of a half-cycle pulse and a short nonresonant laser pulse produces a strongly enhanced postpulse orientation. Robust transients that display both efficie…
Pulse-driven quantum dynamics beyond the impulsive regime
D. Daems, S. Guérin, H. R. Jauslin +2
We review various unitary time-dependent perturbation theories and compare them formally and numerically. We show that the Kolmogorov-Arnold-Moser technique performs better owing t…
Time-dependent unitary perturbation theory for intense laser driven molecular orientation
D. Sugny, A. Keller, O. Atabek +3
We apply a time-dependent perturbation theory based on unitary transformations combined with averaging techniques, on molecular orientation dynamics by ultrashort pulses. We test t…
Optimized time-dependent perturbation theory for pulse-driven quantum dynamics in atomic or molecular systems
D. Daems, S. Guérin, H. R. Jauslin +2
We present a time-dependent perturbative approach adapted to the treatment of intense pulsed interactions. We show there is a freedom in choosing secular terms and use it to optimi…
Reaching optimally oriented molecular states by laser kicks
D. Sugny, A. Keller, O. Atabek +4
We present a strategy for post-pulse orientation aiming both at efficiency and maximal duration within a rotational period. We first identify the optimally oriented states which fu…
