We describe a programmable spectral-phase, pulse-shaping system for femtosecond pulses based on a deformable membrane mirror. Accurate spectral phase design as well as pulse intensity modulation was achieved with direct control of the mirror surface by use of a negative-feedback, mirror-surface control mode. Convergence to the chosen spectral-phase design was typically achieved within several seconds. The pulses were measured with a real-time, second-harmonic-generation, frequency-resolved optical gating system.
