Abstract

The paper introduces an experimental scheme for measuring the phase of double laser pulses based on the combination of near-field time-stretched dispersion Fourier transform(TS-DFT) and Gerchberg-Saxton(GS) algorithm. The scheme uses dispersive fibers to perform near-field dispersion Fourier transform on the double pulse signal, and then uses the GS algorithm of time domain simulation to complete the phase recovery of the double laser pulses. Finally, the algorithm simulation of this scheme successfully recovered the phase information of the double pulses, which verified the feasibility of the scheme.
