Universal long-wavelength nonlinear optical response of noble gases
M. Kolesik, E. M. Wright
We demonstrate numerically that the long-wavelength nonlinear dipole moment and ionization rate versus electric field strength for different noble gases can be scaled onto each…
Space-time resolved simulation of femtosecond nonlinear light-matter interactions using a holistic quantum atomic model: Application to near-threshold harmonics
M. Kolesik, E. M. Wright, J. Andreasen +3
We introduce a new computational approach for femtosecond pulse propagation in the transparency region of gases that permits full resolution in three space dimensions plus time whi…
Microscopic model for the higher-order nonlinearity in optical filaments
A. Teleki, E. M. Wright, M. Kolesik
Using an exactly soluble one-dimensional atomic model we explore the idea that the recently observed high-order nonlinearity in optical filaments is due to virtual transitions invo…
Femtosecond filamentation in air and higher-order nonlinearities
M. Kolesik, E. M. Wright, J. V. Moloney
According to a recent experiment, the instantaneous electronic Kerr effect in air exhibits a strong intensity dependence, the nonlinear refractive index switching sign and crossing…
Dynamic Nonlinear X-waves for Femtosecond Pulse Propagation in Water
M. Kolesik, E. M. Wright, J. V. Moloney
Recent experiments on femtosecond pulses in water displayed long distance propagation analogous to that reported in air. We verify this phenomena numerically and show that the prop…
Polarization dynamics of femtosecond pulses propagating in air
M. Kolesik, J. V. Moloney, E. M. Wright
Polarization dynamics of femtosecond light pulses propagating in air is studied by computer simulation. A rich variety of dynamics is found that depends on the initial polarization…
