高次谐波产生波长依赖性中的量子路径干涉

Quantum path interference in the wavelength dependence of high-harmonic generation

K. Schiessl, K. L. Ishikawa, E. Persson, J. Burgdörfer

摘要:

我们调查的辐射强度的依赖性,由于高次谐波产生(HHG)作为基本驱动场的波长的函数。叠加在一个光滑的幂律依赖先前观察到的,我们发现令人惊讶的强大和快速波动的精细波长尺度。我们确定了这些波动的量子路径干扰的起源与多达五个返回轨道显着贡献。

英文摘要:

We investigate the dependence of the intensity of radiation due to high-harmonic generation (HHG) as a function of the wavelength of the fundamental driver field. Superimposed on a smooth power-law dependence observed previously we find surprisingly strong and rapid fluctuations on a fine wavelength scale. We identify the origin of these fluctuations in terms of quantum path interferences with up to five returning orbits significantly contributing.
