venteon vCHIRP

vCHIRP is a software tool allowing you to calculate the dispersion characteristics of a femtosecond laser pulse propagating through various media and elements and provides information on the best method to obtain a re-compressed pulse.

vCHIRP is especially designed for the ultra broadband femtosecond lasers and the GDD mirrors. In addition, vCHIRP supports many optical elements, such as grating compressors, and template pulses, such as Gaussian pulses or user-measured spectra. Using vCHIRP you can tweak your ultrafast experiment for optimal pulse recompression at the place of interest.


  • Dispersion and pulse compression calculations for designing your ultrafast experiment
  • Featuring the dispersion characteristics of DCM7 & 9 dispersion compensating mirrors
  • Huge material database to select the dispersion characteristics a wide range of glass materials such as BK7, Fused Silica, BaF2, CaF2, Sapphire
  • Next to DCMs various components for dispersion management included, e.g. prism sequences and grating stretchers
  • Easy drag and drop handling of desired components
  • Easy file input function for loading user spectra, the generation of Gaussian spectra or loading SPIDER data
  • Illustration of the different single material GDs and GDDs
  • Plot of the overall dispersion curves (sum) and theoretical achievable pulse duration
  • Export function for all data in various file formats
  • Multiple dispersion files operable at once to test several arrangements at once
  • Developed in cooperation with Prof. Uwe Morgners group at the IQ - Leibniz Universität Hannover
  • Freeware version available free of charge. Full version with all available functions unlocked available on request
