受限原子的高次谐波产生

High-harmonic generation from a confined atom

Carla Figueira de Morisson Faria, Jan-Michael Rost

摘要:

原子在强激光场中发射的高次谐波的阶数受到所谓截止频率的限制。通过求解含时薛定谔方程,我们证明了如果适当地选择约束参数,抛物型约束势可以显著地提高该频率。此外,由于限制,辐射强度在整个扩展的发射范围内保持高。观察到的所有特征都可以用经典的论点来解释。

英文摘要:

The order of high harmonics emitted by an atom in an intense laser field is limited by the so-called cutoff frequency. Solving the time-dependent Schrödinger equation, we show that this frequency can be increased considerably by a parabolic confining potential, if the confinement parameters are suitably chosen. Furthermore, due to confinement, the radiation intensity remains high throughout the extended emission range. All features observed can be explained with classical arguments.
