Abstract

In order to excavate rock bed without reaction, the CO2 laser was utilized. Feasibility of using laser energy to excavate rock was evaluated. Two kinds of rock were subjected to CO2 laser beam preliminary experiment. The cross section of rock samples subjected to CO2 laser was observed carefully along the depth from the irradiated surface.
