Laser technology has revolutionized industries, spanning from manufacturing to healthcare. Lasers, which function by directing super-concentrated light waves to accomplish tasks, have rapidly evolved to become ubiquitous in nearly every application. Be it laser cutting technology or medical laser technology, lasers are essential in promoting productivity, precision, and advancement.
In this article we will learn about the laser types, laser uses, and laser future, and how laser technology is changing our world.
What Is Laser Technology?
Laser—stands for Light Amplification by Stimulated Emission of Radiation. This is an acronym for devices that emit highly concentrated beams of light (laser beams) by stimulating atoms to emit photons. Laser light differs from ordinary light in that it is monochromatic, coherent, and highly directional, which provides the ability to do many high-precision tasks.
In August of 1960, Theodore Maiman invented the first laser. Since that time, lasers have developed and found their use in various fields—telecommunications, medicine, production, and science.
