Laser Beam Technology and Applications

- Overview

Laser beam technology is the use of a device that emits a concentrated beam of light with a specific wavelength and direction. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". 

Electrons are excited by an energy source, such as an electrical current or light. The excited electrons jump to a higher energy level. When the electrons fall back to a lower energy level, they release photons. The photons are sent through an optical medium, such as a gas or solid material. A mirror bounces the photons back toward the electrons. The photons are amplified and move in unison through the optical medium and past the mirrors

- Applications of Laser Beam Technology

Laser beam technology is the use of coherent light beams for many applications, including manufacturing, medicine, and communication. Lasers are versatile tools that can be used for cutting, engraving, drilling, and marking materials.

Applications:

• Manufacturing: Lasers are used to cut, drill, and mark materials for a variety of products. For example, lasers are used to make parts for computers and other electronics.
• Medicine: Lasers are used in many surgical procedures, such as LASIK eye surgery. Lasers can also be used for tooth whitening and other dental procedures.
• Communication: Lasers are used to transmit data and telephone conversations over optical fibers. They are also used in bar code scanners. 
• Space communications: Laser beams are used to transmit microwave bands
• Entertainment: Lasers are used in DVD and Blu-ray players to read information from disks. They are also used to play music, movies, and video games.
• Scientific research: Lasers are used to study the physics of solids, liquids, and gases. They are also used in spectrometers to determine what things are made of.
• Alignment: Lasers are used for alignment purposes in manufacturing processes.  
• Printing: Laser beams are used in laser printers
• Bar coding: Laser beams are used in bar code scanners
• DVD players: Laser beams are used in DVD players
• Electronics: Laser beams are used to make parts for computers and other electronics
• Spectrometers: Laser beams are used in instruments called spectrometers
• Welding: Laser beams are used to weld bioplastic materials and food packaging materials
