Description
Summary:In this paper, ultraviolet laser with the wavelength of 248 nm was employed to assess the laser-induced plasma transmission spectroscopy of four kinds of sandstone. The research focused on the interactions between the laser pulse and the component as well as the structure of sandstone. The more complex metal ion content the rock has, the larger voltage signal the sandstone shows with the same bias current applied. The metal ion can stimulate the formation of plasma excited by the laser. Meanwhile, the excited plasma moves faster in the sandstones with more pores and gives the rock a shorter rise time. The measured voltage effect in sandstone indicates that ultraviolet laser is an approach to identify lithology of stratum by the peak values and rising times.
