Applications Of Laser

APPLICATIONS OF LASER: Lasers are widely used for the following purposes:
1. Measurement of distances: With the help of laser beam, distances can be accurately measured such as the distance of moon from earth.
2. Communication: Lasers play the essential role in using thin strands of glass fibres to transmit light signals that can be received and translated into communication format.
3. Material Processing: Lasers are used in cutting, welding and drilling with more accuracy and precision in even very hard materials because of their very high intensity.
4. Medical Science: Lasers are used to burn up brain tumour and to remove tattoos. Laser welding is also used reconnect blood vessel. Eye surgeons also use laser for ophthalmic operations like treatment of cataract, glaucoma and diabetic retinopathy.
5. Applications in Physics and Chemistry: Laser can be used to study the non-linear optics with special mention of harmonic generation and stimulated scattering. Lasers are also used for producing irreversible chemical change i.e., laser photochemistry.
6. Lasers are used in printing technology.
7. Lasers are used effectively and efficiently in holography to analyse holograms with more precision.
8. Laser beam being of very high energy, has been mentioned as potential “death ray” type of incendiary weapon for use against energy missiles.
