在这项工作中，通过使用时间脉冲预展宽，扩展了最近提出的相位恢复技术的适用性。作为概念的验证，实验分析了由亚皮秒被动锁模光纤激光器和掺铒光纤放大器组成的两级激光系统的光脉冲。将这些结果与基于Gerchberg-Saxton递归算法的两种间接相位恢复技术和分析亚皮秒光脉冲时的强度自相关方法进行了比较。
In this work, the applicability of a recently proposed phase recovery technique is extended, by using temporal pulse pre-stretching. As a proof of concept, the light pulses emitted by a two-stage laser system consisting of a sub-picosecond passively mode-locked fiber laser followed by an erbium-doped fiber amplifier were experimentally analyzed. These results were successfully compared with two indirect phase recovery techniques, both based on the Gerchberg–Saxton recursive algorithm and with the intensity autocorrelation when sub-picosecond light pulses were analyzed.
