An acousto-optic programmable dispersive filter (AOPDF) is a special type of collinear-beam acousto-optic modulator[1] capable of shaping spectral phase and amplitude of ultrashort laser pulses. AOPDF was invented by Pierre Tournois.[2]

Theory of operation[edit]

Traveling acoustic wave induces variations in optical properties thus forming a dynamic volume grating.

Pulse shaping[edit]

AOPDF is a programmable spectral filter.
