Chirped periodic and localized waves in a weakly nonlocal media with cubic-quintic nonlinearity

We study the propagation of one-dimentional optical beams in a weakly nonlocal medium exhibiting cubic-quintic nonlinearity. A nonlinear equation governing evolution beam intensity is derived thereby which allows us to examine whether traveling-waves exist such material. An efficient transformation applied obtain explicit solutions envelope model presence all material parameters. find that variety periodic waves accompanied with chirp do system weak nonlocality. Chirped localized dips on continuous-wave background as well solitary bright and dark types are obtained long wave limit. class propagating chirped self-similar also identified consideration inhomogeneities media. The applications structures discussed by considering distributed amplification system.
