Abstract :
We present a novel construction of a deformable mirror femtosecond pulse shaping. The performance of mirror in ultrafast pulse shaping, we used it to compress long stretched pulses. Pulses from Ti:Sapphire oscillator were propagated through 10 cm long SF11 glass, which introduced about 19000 s2 second order group velocity dispersion. as well as non negligible higher order terms. Then the pulses were send to compressor containing mirror. An evolutionary algorithm, with two photon photodiode as a feedback signal, was used to find the best set of voltages, resulting in the shortest pulse. We were able to get close to the Fourier limited pulse in a few minutes time.
