Temporal imaging of both the intensity and the phase is important for investigating ultra-short events such as rogue waves or mode-locked laser dynamics in a record high resolution. We developed a temporal phase retrieval scheme based on several overlapping time-lenses, where all the time-lenses use the same fibers and detectors leading to high stability and low noise levels. We show that our phase retrieval technique converges faster than techniques that resort to a single time-lens, together with the Fourier transform of the signal.

通过一系列重叠的时间透镜进行相位检索

强度和相位的时间成像对于研究超短事件（如流浪或锁模激光动力学）具有创纪录的高分辨率非常重要。我们基于几个重叠的时间透镜开发了一个时间相位检索方案，其中所有时间透镜都使用相同的光纤和检测器，从而实现了高稳定性和低噪声水平。我们证明了相位检索技术的收敛速度快于采用单个时间透镜以及信号的傅立叶变换的收敛速度。
