laser

When a laser beam collides with material, the laser pulse heats, melts, and vaporizes it. During the process, the vaporized material rapidly increases in volume. The pressure created quickly expels the vaporized material, leaving behind the laser-drilled hole. The greater the energy in the pulse, the larger the hole, and this can be controlled with great precision. Laser drilling allows for very exact location, and accurate hole size. Pulsed lasers can be carefully controlled and rapidly charged. These characteristics lend it to drilling at elevated rates in a given amount of time. It is simple, clean, and fast. This is the most basic form of laser drilling. This process led to several variations of laser drilling, including percussion, trepanning, and helical. Percussion drilling is fairly similar to single pulse. Instead of using one burst of energy, it reduces the power and uses several shorter bursts at the lower energy. Using the percussion method, holes can be deeper, more accurate, and hole diameters can be made even smaller due to less material vaporizing with each rapid pulse
