A basic optical setup including an acousto-optic programmable dispersive filter (Dazzler) has been used to fully characterise an ultrashort pulse. A baseband FROG technique has been used to measure the pulse, with pulse replica creation and inter pulse delay controlled by the Dazzler. The system has been calibrated with Fourier transform spectral interferometry to ensure that dispersion calculated for the Dazzler crystal was accurate. A 12.2 fs pulse was measured with the Phazzler, which as far as we are aware is the shortest pulse measured in such a device.
