METHOD AND DEVICE FOR MEASURING OF PHASIC CHARACTERISTICS AND TERMS OF ONE OR MORE ULTRASHORT LIGHT IMPULSES

摘要

The invention relates to laser optics and can be used for measuring method and device of phasic characteristics and terms of one or more ultrashort light pulses. New is that a conversion of phasic characteristics and terms of pulses of a second harmonic radiation effects using a spatial filtration and registration of a plane image of scanning and a diameter of a second harmonic radiation. A term of pulse as a function on a diameter of a second harmonic radiation is measured by direct mathematical processing of a plane image. A change of a time phase in a term of a pulse is estimated by a spectrum frequency function on an angle of radiation scanning.
