Carsten Brée (WIAS, Laser Dynamics).

Project Description

The goal of the project is the development, validation, and application of an accurate and fast pseudospectral method for solving the multidimensional generalized nonlinear Schrödinger equation, which describes pulse propagation in a hollow waveguide. Numerical integration utilizes a Runge-Kutta scheme for the entire equation. The propagation model contains dispersion, pressure variation, Kerr nonlinearity and plasma generation in the multiphoton and tunneling regime. It is of particular interest to understand the experimentally observed pulse fragmentation, which is indicated by a kink of the spectral phase. The findings on the underlying mechanisms are to be used for avoidance of such phase kink artifacts and for reaching efficient spectral broadening which enables optimum compression. Results from the numerical simulations at the WIAS are to be immediately compared to experimental data from the MBI.
