9 May 2018 Femtosecond laser pulses self-trapping at THG

Self-trapping of laser sub-pulses with basic and triple frequencies propagating in a medium with cubic nonlinear response under THG process is predicted. It appears due to cross- and self-modulation of laser pulses as well as due to SOD influence on interacting waves. Under certain conditions a sequence of sub-pulses or the single color sub-pulse with high intensity is appeared. If the sequence of the sub-pulses occurs they propagate separately each other. Observed sub-pulse formation can be used for generation of attosecond pulses at both frequencies with soliton or soliton-like shape.
