Propagation patterns of pump and Stokes breathers of the transient stimulated Raman scattering system in gas-filled hollow-core crystal fibers

In this article, under investigation is the optical pulse propagation of the transient stimulated Raman scattering (TSRS) system in gas-filled hollow-core crystal fibers. The pump and Stokes breather solutions are constructed via Darboux transformation (DT) method. Novel spatio-temporal propagation patterns of breather waves are observed. The results show that the pump and Stokes breathers not only have rich phase patterns, but also demonstrate certain complementarity.
