TY - CHAP AB - We investigate the spatiotemporal characteristics of subpicosecond pulse propagation in the nonlinear defocusing regime below the band edge of bulk GaAs. We observe temporal and spatial pulse compression and instabilities. AU - Nielsen, N. C. AU - zu Höner Siederdissen, T. AU - Kuhl, J. AU - Schaarschmidt, M. AU - Förstner, Jens AU - Knorr, A.
