We propose an all-diffractive pulse shaper for arbitrary waveform generation in the femtosecond regime. This optical device improves in several aspects the performance of our previous quasi-direct pulse shaper reported in Mínguez-Vega et al. [Opt. Express16, 16993 (2008)]. In the present implementation, by using grayscale masks we can achieve arbitrary temporal waveforms. Additionally, the holographic reconstruction of the above masks by means of phase holograms allows for a high-efficiency shaping process. The behavior of the pulse shaper is tested by numerical simulations.
我们提出了一种用于飞秒域任意波形产生的全衍射脉冲整形器。该光学器件在几个方面改进了 Mínguez-Vega 等人之前报道的准直脉冲整形器的性能。[Opt. Express16, 16993 (2008)]。在目前的实现中,通过使用灰度掩模,我们可以实现任意的时域波形。此外,通过相位全息图对上述掩模进行全息重建,可以实现高效的整形过程。通过数值模拟测试了脉冲整形器的性能。
