Abstract
. -- We present the combination of microscopic model calculations and direct experimentalevidence for complex spatio-temporal dynamics on a picosecond timescale in the nearfieldof a broad-area semiconductor laser induced by the interplay of self-focusing, di#raction,and spatial hole burning. We demonstrate the formation of migrating optical filaments withinthe turn-on dynamics of such a laser and characterize the resulting spatio-temporal complexityvia spatio-temporal cross-correlation...Keywords
