Applications of Laser:
Due to its properties, laser light can be put to a number of uses in industry, medicine, communications etc. We will briefly describe some of these uses. Because of the high concentratior, of energy, a laser beam can quickly bum tiny holes, a few millimetres wide, even in a strip of steel. Lasers have an advantage over all other traditional methods of cutting and welding. Using lasers you can cut any kind of material. such as paper, plywood, plastic or cloth, as also the hardest of metals, ceranlics and glass with greater efficiency and accuracy. Lasers can, thus, make an ideal tool for metal workers, carpenters and tailors, apart from engineers.
