Abstract: Complex dynamics of femtosecond terawatt laser pulses in air is investigated theoretically and numerically by considering both (5) susceptibility and multiphoton ionization. Our investigation shows that these two high-order nonlinearities, acting as a Hamiltonian perturbation, can destroy homoclinic orbit connection of phase trajectory and result in spatial chaos and complex pattern of laser wave field. Due to the chaotic behavior of laser field, laser filamentation appears when laser intensity increases close to the ionization threshold. © 2007 American Institute of Physics.
