Abstract
 
In this paper, high-harmonic generation and ionization probability is investigated in both laser homogeneity electric field and plasmonic inhomogeneity field enhancement for a hydrogen gas. The plasmonic electric field caused by the collision intense beams of laser with metallic nanostructures. To study high‌-harmonic generation is used the semi-classical model using the strong-field approximation. Ionization probability is investigated by ADK method. The results of the model indicate that the harmonic cutoff increase because of the plasmonic field enhancement and shorter attosecond pulses can be obtained.
