“…It has been noted, in particular, that a soliton on one transition of a V-system may enhance transmission of a weak pulse on the other transition even if the latter has a different oscillator strength [10]. The soliton may amplify the weak pulse and transport it through the medium simulton-like [11,12]. The term soliton-induced transparency has been coined for this effect [11].…”

The propagation of two-color laser fields through optically thick atomic ensembles is studied. We demonstrate how the interaction between these two fields spawns the formation of co-propagating, two-color soliton-like pulses akin to the simultons found by Konopnicki and Eberly [Phys. Rev. A 24, 2567 (1981)]. For the particular case of thermal Rb atoms, exposed to a combination of a weak cw laser field resonant on the D1 transition and a strong, sub-ns laser pulse resonant on the D2 transition, simulton formation is initiated by an interplay between the 5s 1/2 -5p 1/2 and 5s 1/2 -5p 3/2 coherences which amplifies the D1 field at the arrival of the D2 pulse producing sech-squared pulse with a length of less than 10 microns. This amplification is demonstrated in a time-resolved measurement of the light transmitted through a thin thermal cell. We find good agreement between experiment and a model that includes the hyperfine structure of the relevant levels. With the addition of Rydberg dressing, quasi-simultons offer interesting prospects for strong photon-photon interactions in a robust environment. arXiv:1909.07161v1 [physics.atom-ph]
