摘要:

通过对驱动激光和高次谐波的量子化,提出了高次谐波产生的光子通道观点。结果表明,高次谐波产额可以表示为所有光子通道的贡献之和。从这个角度来看,一个特定的光子通道的贡献遵循一个简单的标度律和通道之间的竞争很好地解释。通过求解含时薛定谔方程,我们的预测与模拟结果吻合得很好。它也能很好地解释非共线双色场和双极激光场中高次谐波的实验结果。

英文摘要:

Photon channel perspective on high harmonic generation (HHG) is proposed by quantizing both the driving laser and high harmonics. It is shown that the HHG yield can be expressed as a sum of the contribution of all the photon channels. From this perspective, the contribution of a specific photon channel follows a simple scaling law and the competition between the channels is well interpreted. Our prediction is shown to be in good agreement with the simulations by solving the time-dependent Schrodinger equation. It also can well explains the experimental results of the HHG in the noncollinear two-color field and bicicular laser field.
