Laser Technology
Technology has provided us numerous miraculous discoveries and devices. Lasers are its most modern achievements. Lasers are defined as the devices which produce pure and intense beams of light or radiation. Lasers are widely used in the field of industry. They are used in cutting clothes, piercing leather and even hard substances like diamond and metals, and cutting bricks and granite. Similarly, they are also used in welding. They can also be used in transport and communication: for example, they are used instead of cables in telecommunication, and they are used in flight simulations to train pilots. Thus lasers are enormously used in the field of industry, transport and communication.
In the field of medicine, lasers have made a revolution. Lasers are used to destroy the single cell of living tissues in the treatment of cancer. Doctors have been using lasers instead of surgical knives in major operations. Lasers can help us in pollution control. They are useful for measuring the size of pollutant particles in the air. They can also be used for measuring the distance between two objects, such as between the moon and the earth. Thus they are used in the field of medicine, pollution control and measurement.
