In this paper we introduce a pseudospectral shooting method to model intense, ultrashort optical pulses incident on remote targets. The method naturally extends the unidirectional pulse propagation equation to include backward propagating radiation due to either nonlinear coupling with the “forward” field or reflections generated at material boundaries. The general applicability of the method is highlighted with several examples, including a full simulation of a pulse propagating through air across an ultrathin gold film coated on fused silica.
