The femtosecond time scale is out of reach for even the fastest electronics, so to perform pulse diagnostics other measurement techniques need to be used.
The AvaSoft-Femto add-on turns your Avantes spectrometer into a femtosecond laser diagnostic tool that can provide you with an estimation of the transform limited pulse duration as well as measuring
the peak wavelength and relative intensity of the laser output. Using the add-on users can also easily export the measurements to spread sheet programs like Microsoft Excel for record keeping or further analysis.
Avantes spectrometers, in combination with the proprietary AvaSoft-Femto spectroscopy software, can be used for femtosecond laser measurements
