Abstract:
An analysis is made of the operation of a three-channel correlator used in the determination of the time dependences of the intensities of single ultrashort laser pulses of arbitrary structure. The control channels of the correlator have switches based on the quadratic electrooptic effect. The fifth-order correlation function I(5)(τ1, τ2, τ3, τ4) with τ1 = τ2, τ3 = τ4 is recorded at the correlator exit. The proposed and analysed procedure for the processing of the recorded information makes it possible to determine the structure of an optical signal in the form I(t). The procedure is based on the conversion of the signal to the spectral representation and the use of the real part as well as of the derivative (with respect to the frequency ω3) of the imaginary part of I(5)(ω1, ω3) when ω3 = –ω1.
