论文摘要
根据实时的从头算计算，我们研究了在强场状态下两色激光脉冲与MGO晶体的非扰动相互作用，以从MGO晶体中产生来自MGO晶体的高谐波排放的分离的Attosent脉冲。在这方面，我们检查了入射脉冲特征的影响，例如其形状，强度和椭圆形，以及晶体各向异性对发射谐波及其相应孤立的attosecond脉冲的影响。我们的计算预测，持续时间约为300次的分离量脉冲的创建；此外，使用椭圆驱动脉冲，显示了椭圆形的分离量脉冲的产生。我们的工作为所有固态紧凑型光学设备的路径做好了准备，这些光学设备提供了除了原子发出的传统隔离脉冲之外的视角。
On the basis of real-time ab initio calculations, we study the non-perturbative interaction of two-color laser pulses with MgO crystal in the strong field regime to generate isolated attosecond pulse from high-harmonic emissions from MgO crystal. In this regard, we examine the impact of incident pulse characteristics such as its shape, intensity, and ellipticity as well as the consequence of the crystal anisotropy on the emitted harmonics and their corresponding isolated attosecond pulses. Our calculations predict the creation of isolated attosecond pulses with a duration of ~ 300 attoseconds; in addition, using elliptical driving pulses, the generation of elliptical isolated attosecond pulses is shown. Our work prepares the path for all solid-state compact optical devices offering perspectives beyond traditional isolated attosecond pulse emitted from atoms.
