Description
On the basis of real-time {\it 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 (IAP) 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 IAPs.
Our calculations predict the creation of IAPs with a duration of $\sim$ 300 attoseconds;
in addition, using elliptical driving pulses, the generation of elliptical IAPs is shown.
Our work prepares future all solid-state compact optical devices offering perspectives beyond traditional IAP emitted from atoms.
