  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.
