Nonlinear Effect Of An Ultrashort Laser Pulse Propagation In Ti:Sapphire Crystal

Impact of such terms as third order dispersion, self-steepening and stimulated Raman scattering on evolution of ultrashort pulses is considered in detail. Under influence of these effects, pulse did not maintain its initial shape in the case of the silica fiber. Pulse splits into constituents, its spectrum also evolving into several bands which are known as optical shock and self-frequency shift phenomena. We concluded that when the input peak power is large enough, dynamics of pulse splitting will be complicated. We propose in this article, a new generation of the fiber type; the Ti:sapphire crystal fiber which is able to solve these problems of writings before. Our numerical simulations were in good agreement with the Ti:sapphire crystal fiber One basing itself on the resolution of the nonlinear Schrodinger equation.
