Paper Abstract

THG is used nowadays in many practical applications such as a substance diagnostics, and biological objects imaging, and etс. Therefore, THG features understanding are urgent problem and this problem attracts an attention of many researchers. In this paper we demonstrate a formation of sub-pulse comb with subfemtosecond duration at THG of femtosecond laser pulse propagating in a medium with cubic nonlinear response. This pulse comb has a regular structure in many cases of interacting waves. The sub-pulse duration is governed by the incident femtosecond pulse duration. We consider both incident chirped and un-chirped pulse.

Consideration is based on computer simulation of the laser pulse propagation with taking into account a self- and cross- modulation of interacting waves, and their SOD, and phase mismatching. Observed sub-pulse formation can be used for generation of sequence of attosecond pulses with soliton or soliton-like shape.
