A first order theory of operation of the acousto-optic programmable dispersive filter used for femtosecond laser pulse optimization and shaping is presented. The filter spectral resolution, angular aperture, number of programming points, diffraction efficiency as a function of acoustic power are addressed. The theory takes into account the dispersion effects induced by the Tellurium dioxyde crystal, Wideband or high resolution operations of the filter lead to two different crystal cut optimizations.
