Ultrafast light-matter interaction in transparent medium
The ultrafast interaction between high power laser light and plasma has been studied theoretically. The theoretical simulations are based on the nonlinear Schrödinger equation taking into account group velocity dispersion, diffraction, self-focusing and multiphoton absorption. The plasma is forme...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The ultrafast interaction between high power laser light and plasma has been
studied theoretically. The theoretical simulations are based on the nonlinear Schrödinger
equation taking into account group velocity dispersion, diffraction, self-focusing and
multiphoton absorption. The plasma is formed during propagation of femtosecond laser
pulse with high input power in transparent medium due to multiphoton ionization
process. The induced plasma results in light scattering with formation of multiple cones.
It was found that plasma forms cone region that is inverse to cones appearing from
scattering of electromagnetic field. The Fourier transformation of temporal-spatial
dependences of plasma density demonstrates formation of quasi-periodic structure for
plasma waves. |
