Synthesis of ultrafast waveforms using coherent Raman sidebands

In this work, we implement a scheme to combine six coherent, spatially separated Raman sidebands generated in single-crystal diamond into a collinear beam. With appropriate phase tuning, this results in a pulse much shorter than the generating pump. We elucidate the characteristics of the synthesized pulse by using an interferometric collinear cross-correlation frequency-resolved optical gating setup (ix-FROG). The beating of the synchronized sidebands results in an additional component in the signal, which we use to optimize the relative phases of our sidebands. In this way, we synthesize and measure visible-range, near-single cycle isolated pulses of approximately 5 fs total pulse duration.

使用相干拉曼边带合成超快波形

在这项工作中,我们实现了一个方案,将单晶金刚石中生成的六个相干,空间上分开的拉曼边带组合成共线光束。通过适当的相位调整,这将导致脉冲比发电泵短得多。我们通过使用干涉共线性互相关频率分辨光学选通装置(ix-FROG)阐明了合成脉冲的特性。同步边带的跳动会在信号中产生额外的分量,我们可以使用它来优化边带的相对相位。这样,我们合成并测量了总脉冲持续时间约为5 fs的可见范围,近单周期隔离脉冲。
