A laser is made up of electronic magnetic radiation, which is amplified through optical lenses to increase the strength of the light emitted. The term "laser" means Light Amplification by Stimulated Emission of Radiation. The radiation emitted by lasers is not enough to contaminate or cause significant damage to organic tissues, unless the tissue is in the direct path of the laser. Lasers are classified into two types; continuous and pulse modes of operation. They have been modified for a variety of different uses in daily life.
Functioning Lasers in Daily Life
Wart Removal - The intense light of a laser has been used to remove unwanted warts and skin tags on people. The concentrated light is precise enough to target small areas, while using an intense light.
Laser Hair Removal - Laser hair removal has become a popular way of removing body hair. Most lasers are relatively weak, but strong enough to penetrate just below the skin and destroy hair follicles. It usually takes a few treatments to be effective.
Laser Eye Surgery - This type of surgery requires the preciseness of a laser and intensity to burn through certain tissues, while leaving others untouched. The beam is focused on the damaged part of the eye and burns away damaged tissue.
Laser Fiber Optics - Fiber optics are one of the most important materials used in modern society. They are an integral part of computer networking and the Internet.
Disc Readers - CD players and disc drives use small lasers to read and transfer data information between electronic devices.
