What is CO2 Laser Drilling Effects on Rock Types about?

This document summarizes a study that investigated the effect of CO2 laser parameters on drilling characteristics when drilling different types of rocks. The study tested different combinations of laser power, frequency, piercing time, and assist gas pressure on samples of limestone, sandstone, and shale. For limestone, the minimum specific energy and maximum rate of penetration were achieved at 1000 W laser power, 1 kHz frequency, 6 bar assist gas pressure, and 0.1 s piercing time. For sandstone, the best
