## Abstract

Interaction of ultera-short laser pulses with a dense cold plasma is investigated. Due to high density, of plasma, quantum effects such that Bohm potential and quantum pressure should be considered. The results reveal that electron density function modulated by laser light in the propagation direction. This modulation can be controlled by amplitude of laser intensity and plasma effective parameters. For some special values of involved parameters electron density become localized in quenches spatially. Increasing the quantum coefficient tends to rarefy the high electron density regions, since the total number of electrons are constant. Hence, our theory predicts plasma expansion in the direction of laser light due to quantum effects.
