摘要
The present application relates to a method and system for characterization and compression of ultrashort pulses. It is described a flexible self-calibrating dispersion-scan technique and respective system to characterize and compress ultrashort laser pulses over a broad range of pulse parameters, where previous knowledge of the amount of dispersion introduced for each position or step of the compressor is not required. The self-calibrating d-scan operation is based on the numerical retrieval of the spectral phase of the pulses using an optimization algorithm, where the spectral phase is treated as a multi-parameter unknown variable, and where the unknown dispersion of the dispersion scanning system is described by a theoretical model of its functional dependence on the compressor position.
