  Time Shaping of ultrashort visible pulses has been performed using a
specially designed Acousto-Optic Programmable Dispersive Filter of 50%
efficiency at the output of a two-stage noncollinear optical parametric
amplifier. The set-up is compact and reliable. It provides a tunable shaped
source in the visible with unique features: 4 ps shaping window with preserved
tunability over 500-650 nm, and pulses as short as 30 fs. Several $\mu$J output
energy is easily obtained.
