Laser drilling uses powerful beams of light to vaporize materials and drill precise holes without mechanical means. It is used in precision machining and drilling hard or fragile materials. Powerful lasers may also be used for mining and oil extraction.
Laser drilling is the process of drilling holes using lasers. This can be done on a small scale, such as drilling very small holes in machine parts, or on a larger scale, such as larger holes in materials that don’t hold up well with normal drilling techniques. Lasers are devices that generate powerful beams of light by concentrating highly energized photons. These powerful beams of light are capable of vaporizing the materials they are trained on and can be focused very precisely, allowing them to be used for cutting and drilling.
Modern lasers are capable of focusing large amounts of energy in the form of beams of light. These rays of light, just like the beam of a lighthouse or flashlight, are generally not visible in the air, but only when they strike some kind of matter. Dust or even water vapor in the air, in the form of vapor or mist, can make them visible as some of their light is reflected off the tiny particles. They are also visible as a point of light when they encounter solid matter.
If the laser is powerful enough, it can cause matter to overheat, and when very powerful lasers are focused on a material, they can generate enough local heat to melt or even vaporize the material in a very localized area. Laser drilling uses this principle to drill holes in various materials. Using lasers in this way allows holes to be made quickly and efficiently without drill bits or mechanical means.
Many precision machining processes benefit from the use of laser drilling. For example, laser drilling allows very small angular holes to be made with great precision in very hard materials, such as titanium, which can be difficult to accurately machine drilling techniques. This type of laser drilling is often used in the aviation industry. Laser drilling is also used to drill holes in materials that tend to crack, shatter, or chip when drilled with conventional power drills. Lasers are also used to drill very small holes that are impossible to make by any other means.
It is thought that very powerful lasers can also be used to pierce the earth. Researchers are developing lasers of this type to be used for mining and extracting crude oil. Some of the more powerful drilling lasers may be able to drill through rock very quickly and greatly increase the accuracy and speed of this type of drilling over traditional methods.
