Applications of Laser
Laser technology has revolutionized various industries and scientific fields, offering precise and powerful solutions for a wide range of applications. From industrial manufacturing to medical procedures and from communication to research, lasers have found extensive use due to their unique properties and capabilities. In this article, we will explore the diverse applications of lasers and their impact on different sectors.
1. Introduction to Laser Technology
Lasers, which stands for Light Amplification by Stimulated Emission of Radiation, are devices that emit coherent light through the process of stimulated emission. They produce an intense beam of monochromatic light that can be precisely controlled and focused. This characteristic makes lasers highly versatile and enables their application in various domains.
2. How Lasers Work
Laser operation involves the excitation of atoms or molecules in a medium, which then release photons that stimulate other excited atoms or molecules to release additional photons. This process creates a chain reaction of stimulated emission, resulting in the amplification of light. The amplified light is then reflected back and forth between two mirrors, creating a coherent and focused beam.
3. Industrial Applications of Lasers
