Аннотация:We report a tunable spectral and spatial frequency shaper of ultrashort laser pulses based on multi-frequency acousto-optic diffraction. The experimental setup is based on a Ti:sapphire femtosecond laser. A high-resolution acousto-optic dispersion delay line (AODDL) was used for optical wavelength selection. A multi-frequency RF signal applied to the AODDL provides independent transmission windows that can be arbitrarily tuned between wavelengths of 750 nm and 850 nm. Each transmission window bandwidth could be adjusted from 0.3 to 2.4 nm.
