  • Apparatus and method for in-line measurement of laser pulses with time-dependent polarization
    Patent number: 11105687
    Abstract: An apparatus and a method for in-line measurement of laser pulses with time-dependent polarization are described, which make possible to carry out in-line measurement of laser pulses whose polarization depends on time. For this, one or more polarization projections are selected: the spectrometer detects the projection on the extraordinary propagation axis of a birefringent system to measure the spectrum in that component, also the projection on the ordinary propagation axis, to measure the spectrum in that component, and finally a projection in an intermediate direction that allows to measure the interference spectrum between the two components. The method allows extracting the temporal evolution of the pulse and its polarization state as a function of time, spectral amplitudes and phases of the various polarization projections of the beam.
