我们报道了对由绝热拉曼过程产生的频率间隔为10.6太赫兹的相干离散谱(拉曼边带)的逐行控制。结果表明，拉曼边带的光谱相位可以很好地控制到目标位置(平坦的相对光谱相位)。这是通过使用空间相位控制器和光谱干涉仪的组合来实现的，这是专门为高功率离散频谱而设计的。我们还表明，这种频谱相位控制在时间域中产生了超高重复频率为10.6THz的傅里叶变换有限脉冲序列。
We report line-by-line control of a coherent discrete spectrum (Raman sidebands) with a frequency spacing of 10.6 THz that is produced by an adiabatic Raman process. We show that the spectral phase of the Raman sidebands is finely controlled to the target (flat relative-spectral-phase). This is achieved by employing a combination of a spatial phase controller and a spectral interferometer, which are specifically designed for a high-power discrete spectrum. We also show that such spectral-phase control produces a train of Fourier transform limited pulses with an ultrahigh repetition rate of 10.6 THz in the time domain.
