Laser is an acronym that stands for Light Amplification by Stimulated Emission of Radiation. It is a device that produces a beam of highly concentrated light through the process of stimulated emission. This means that the laser emits light by stimulating the emission of photons from excited atoms or molecules, rather than by heating them up like a traditional light source.
Lasers are used in a wide range of applications, including scientific research, medicine, communication, manufacturing, and entertainment. They are highly precise and can be used to cut, weld, or vaporize materials, as well as to transmit information over long distances.
The first laser was invented in 1960 by Theodore Maiman, who used a ruby crystal as the active medium. Since then, lasers have been developed using a variety of materials, including gases, liquids, and solids, and have been made in many different colors, sizes, and shapes.
Lasers are classified according to their wavelength and the type of material used as the active medium. The most common types of lasers are gas lasers, solid-state lasers, and semiconductor lasers. Each type of laser has unique properties and is used for different applications.
In conclusion, the acronym laser stands for Light Amplification by Stimulated Emission of Radiation and refers to a device that produces a beam of highly concentrated light through the process of stimulated emission. Lasers are used in a wide range of applications and are highly precise and versatile, making them an essential tool in many fields.

Of course even a laser whose output is normally continuous can be intentionally turned on and off at some rate in order to create pulses of light. What are the 3 types of lasers? The label "eye-safe" can be misleading, however, as it applies only to relatively low power continuous wave beams; a high power or Lasers can be a hazard to both civil and military aviation, due to the potential to temporarily distract or blind pilots. Can a laser pointer reach the moon? Light Amplification by Stimulated Emission of Radiation LASER , or as most of us know it, argon laser—excited ions in an argon-filled chamber produce a light that is focused and passed through the handpiece.

Infrared lasers with wavelengths longer than about 1. Mode locking Main article: A mode-locked laser is capable of emitting extremely short pulses on the order of tens of Such mode-locked lasers are a most versatile tool for researching processes occurring on extremely short time scales known as femtosecond physics, Pulsed pumping Another method of achieving pulsed laser operation is to pump the laser material with a source that is itself pulsed, either through electronic charging in the case of flash lamps, or another laser which is already pulsed. Lasers are often described by the kind of lasing medium they use — solid state, gas, excimer, dye, or semiconductor. Retrieved May 22, 2008.
