文摘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.
