The Overview of Laser Drilling Technology

This paper mainly states four aspects about laser drilling technology. It analyzes the principle and advantages of laser drilling. Seven kinds of laser drilling lasers are listed. The characteristics of these lasers are simply introduced. The present state of laser drilling technology researches at home and aboard is specifically summarized, including the researches of groundwater laser rock-breaking, specific energy, rock-breaking patterns of different rocks, rock-breaking time and resin spray casing completion. Meanwhile, compared with the conventional rotary drilling, this article sums up the advantages and the problems of laser drilling, and then puts forward the prospects for the laser drilling research.
