Filamentation in air - poor man's sub 7 fs setup — •Bruno Schmidt, Waldemar Unrau, Adlo Mirabal, Ludger Wöste, and Torsten Siebert — Institut für Experimentalphysik, Freie Universität Berlin, Arnimallee 14, 14195 Berlin, Germany

An optical setup for generation and measurement of few cycle pulses is presented. It comprises spectral broadening via single filamentation in air, standard chirp mirrors for dispersion compensation and a transient grating FROG as characterization. This cheep and robust arrangement enables measuring of pulses as short as 6.4 fs and FROG traces with bandwidths reaching from (370-950) nm for uncompressed supercontinuum.
