- Any experiment using ultrashort laser pulses with a duration of only a few femtoseconds requires a proper dispersion management to actually reach the transform-limited pulse duration at the site of the interaction and thus exploit the full benefit of the ultrashort pulse provided by the laser oscillator. In most cases therefore a characterization tool which allows an easy and reliable measurement of the pulse duration is desired and strongly facilitates the optimization of the dispersion compensation.
- All these requirements can be provided by Spectral Phase Interferometry for Direct Electric-Field Reconstruction (SPIDER*) which is the most powerful technique for robust intensity profile and spectral phase characterization of ultrashort optical pulses.
Compared to other ultrafast pulse characterization techniques SPIDER does not rely on simple fits or uses complex reconstruction algorithms which are mostly very time consuming.
Using SPIDER the spectral phase information of the unknown laser pulse can be extracted by a robust, non-iterative and rapid phase-retrieval procedure introduced by Takeda et al. in real-time.
