Multiphoton population transfer between rovibrational states of HF: adiabatic
... forbidden and the transition occurs through tunnelling. We show that for larger peak intensities, the transfer can be looked upon as a classical transition in phase space, similar to that observed in the atomic case. We extend our simulations to fully three-dimensional quantum calculations and inves ...

Role of dispersion in pulse emission from a sliding
... the amplitude A of the solitary-wave solution [Eqs. (3) and (4)] on the dispersion coefficient D. In Figs. 3 – 5 the linear excess gain d . 0, whereas in Figs. 6 – 8 d , 0. In Figs. 3 – 5 we set b 3d 0.15 and we varied the nonlinear gain (or saturable loss) coefficient from g 0 (dashed curves) ...

New approach to pulse propagation in nonlinear
... Propagation of optical pulses through nonlinear dispersive media is studied in many contexts ranging from optical communications [1] to ultrafast optics [2]. The usual starting point is the nonlinear Schrödinger (NLS) equation, obtained from Maxwell’s equations under the slowly varying envelope appr ...
