Abstract

The spectral phase shift and both types of angular dispersion introduced by an acousto-optic programmable dispersive filter (AOPDF) into a femtosecond laser beam at 800 nm have been measured with high precision. With the use of spectrally and spatially resolved interferometry we experimentally proved that the AOPDF controls the group delay dispersion (GDD) and third-order dispersion with an accuracy of better than 1 % and 3 % of the preset values within the range of 2 fs2 - 1000 fs2 and 1000 fs3 - 40000 fs3, respectively. Both the angular deviation as well as the angular dispersion values are primarily dependent on the set absolute value of GDD of the continuously operating AOPDF. Besides of a small offset value, there is no added angular dispersion at 0 fs2, while this can be as large as 0.2 μrad/nm at 10000 fs2.
