The Spectral Propagation of Ultra-Short Laser Pulses with Sharp Material Interfaces

Series: Modeling and Computation Seminar
Location: Math 402
Presenter: Andrew Hofstrand, Program in Applied Mathematics, University of Arizona

When simulating the complicated propagation dynamics of femtosecond-scale optical pulses through realistic nonlinear materials such as the atmosphere, the Uni-Directional Pulse Propagation equation (UPPE) has been very successful.  The UPPE is a pseudo-spectral representation of Maxwell's equations which assumes only that the pulse travels in one direction.  In this talk we consider how to generalize the UPPE to include backward and transversely propagating fields using an iterative shooting method which takes into account sharp material interfaces and their boundary conditions.
