Abstract

Ultrashort optical pulses with user-desired temporal waveforms are widely applied in the areas of laser control and optical communication. In this paper, by combining the phase iteration and amplitude iteration, a two-step phase-amplitude hybrid algorithm for ultrashort optical pulse synthesis is proposed. Effectiveness of this proposed algorithm is proved by synthesizing two types of ultrashort optical pulses, including a single pulse with different temporal waveforms and a train of pulses with variable intensity envelopes. Compared with the conventional phase-only algorithm, the phase-amplitude hybrid algorithm can effectively reduce the influence of falling into local optimal solution caused by inappropriate initial chosen phase, thus achieving a better accuracy for synthesized pulses.
