LASERS administers 24 retirement plans covering over 150,000 members and their families. Although lasers range from quantum-dot to football-field size and utilize materials from free electrons to solids, the underlying operating principles are always the same. This article provides the basic … Lasers are devices that concentrate beams of light by forcing their waveforms and frequencies to align.

First developed in the 1960s to amplify microwaves, modern lasers technology can ramp up light rays … Lasers may power new forms of data storage, secure communication using quantum encryption, or energy delivery via wireless laser beams. In medicine, researchers are developing lasers … Lasers are amazing light beams powerful enough to zoom miles into the sky or cut through lumps of metal. Although they seem pretty recent inventions, they've actually been with us … What makes lasers useful? We explore how the worlds of relativity, quantum mechanics and light collided to develop a device that revolutionises everyday life. Lasers are used in dental drills, eye surgery, tattoo removal, and (of course) laser pointers. Learn how different lasers generate such concentrated light.

This article provides the basic information about how and why lasers work. Coherent Corp. CO₂ lasers, another variety, are powerful infrared sources used in cutting and welding materials. Semiconductor lasers, or diode lasers, are compact and efficient. They’re the engines behind optical communications, laser pointers, and Blu-ray players. Lasers are devices that concentrate beams of light by forcing their waveforms and frequencies to align. First developed in the 1960s to amplify microwaves, modern lasers technology can ramp up light rays in just about any part of the electromagnetic spectrum, with the exception of gamma waves. Lasers may power new forms of data storage, secure communication using quantum encryption, or energy delivery via wireless laser beams. In medicine, researchers are developing lasers that can diagnose diseases by detecting molecular changes in tissues. Lasers are amazing light beams powerful enough to zoom miles into the sky or cut through lumps of metal. Although they seem pretty recent inventions, they've actually been with us over half a century: the theory was figured out in 1958; the first practical laser was built in 1960. The Dual Edge of Light: Lasers in Warfare Yet, like all powerful technologies, lasers carry a dual edge. The same precision that heals and builds can also harm and destroy. Militaries across the world experiment with laser weapons capable of blinding sensors, disabling drones, or even striking targets with beams of energy. Lasers produce a narrow beam of light in which all of the light waves have very similar wavelengths. The laser’s light waves travel together with their peaks all lined up, or in phase. This is why laser beams are very narrow, very bright, and can be focused into a very tiny spot. This animation is a representation of in phase laser light waves.
