Abstract : The feasibility for femto and attosecond pulse generation from diamond subjected to intense fs laser pulse with mid-infrared wavelength was explored by further investigating the non-perturbative scaling ofthe generated harmonics with the laser field and their bandstructure dependence since recent experimental and theoretical investigations in the literature show that high harmonic generation HHG in wide band-gap semiconductors (insulators) may lead to brighter sources due to the high laser induced carrier density and ability to withstand the driving laser fields necessary for inducing strong nonlinear and non perturbative effects leading to HHG.
