Polarization-interferometric method for measuring the pedestal of femtosecond radiation
We propose a polarizing interferometer based on a crystal anisotropic medium with variable thickness. The results of experimental simulation modelling show that this interferometer can be used to measure the coherence time in a wide time range from a few femtoseconds to tens of picoseconds. This can be used, for example, to control the picosecond pedestal of spectrally limited femtosecond pulses.
