摘要

We propose a simple iterative algorithm based on a temporally movable phase modulation process to retrieve the weak temporal phase of laser pulses.This unambiguous method can be used to achieve a high accuracy and to simultaneously measure the weak temporal phase and temporal profile of pulses,which are almost transform limited.A detailed analysis shows that this iterative method has valuable potential applications in the characterization of pulses with weak temporal phase.
