Abstract

We achieved reliable and stable generation of pulses with all possible polarization states by a Mach-Zehnder pulse shaper. This was realized by incorporating a stabilization mechanism using an external laser diode in the interferometric pulse shaper. This stabilization mechanism has overcome an inherent instability in the Mach-Zehnder interferometer, which caused serious distortion of shaped pulses. For a demonstration of polarization shaping, we generated and measured chiral pulses with a rotating major axis of polarizing orientations at arbitrary frequencies. We expect these chiral pulses enables us to study on new chirality-related light-matter interactions.

摘要

我们通过马赫-曾德尔脉冲整形器实现了具有所有可能偏振态的脉冲的可靠且稳定的产生。这是通过在干涉式脉冲整形器中纳入一种使用外部激光二极管的稳定机制来实现的。这种稳定机制克服了马赫-曾德尔干涉仪中固有的不稳定性，这种不稳定性会导致整形脉冲严重失真。为了演示偏振整形，我们生成并测量了具有在任意频率下旋转的偏振方向主轴的手性脉冲。我们期望这些手性脉冲能使我们研究新的与手性相关的光与物质的相互作用。
