要旨:
Shaping of femtosecond light pulses is typically performed in the frequency domain, by manipulation of the pulse spectral intensity and phase. One tool for phase control uses a deformable mirror in the Fourier plane of a 4-f stretcher. In this work we show the ability of adaptive optics to shape femtosecond pulses. By including the shaper and the characterization block in a closed loop, it is possible to correct spectral phase distortions accumulated in an optical chain in few automatic iterations.
