Self-phase modulation in TIR-PCF under Compton scattering

By using the multi-photon nonlinear Compton scattering conception and the model of the nonlinear scattering between an electron and a photon, the propagation equations of the laser amplification of the coupling chirped-pulse in the total internal reflective photonic crystal fiber are built. By theoretical analysis and numerical simulation, the influences of Compton scattering on the self-phase modulation of TIR-PCF are studies. The results show that the self-phase modulation of the coupling chirped-pulse laser is strengthened by the Compton scattering. The induction electrical polarization strength of the fiber, the density of the reversed particle number and gain increase, the phase changing accelerates, and the excited radiation section decreases. Therefore, the gain phase movement can not be ignored.
