Femtosecond pulse shaping

Femtosecond pulse shaping

Femtosecond pulse shaping is a powerful technique used in ultrafast optics for the generation of ultrashort (femtosecond) laser pulses with complex temporal shapes. A commonly used approach is Fourier transform pulse shaping in which the spectral components of a broadband pulse are spatially separated so that they can be manipulated individually to give desired pulse shape when recombined. We employ a liquid crystal-based pulse shaper for efficient pulse compression and the generation of multi-pulse sequences for multidimensional spectroscopy experiments. We have also developed techniques to compensate for artifacts occurring in liquid crystal light modulators to enable high precision pulse shaping.
