Lasers cut precisely and without contact – ideal for surgery. The problem is that, in hard tissues such as bone, they are too slow and do not cut deep enough. Researchers at the University of Basel ...
A laser is not just light; it is light disciplined, sharpened, and focused into a beam so pure and precise that it can travel across the Moon, cut through steel, perform delicate eye surgery, or carry billions of internet messages in a single second.
Lasers are used in dental drills, eye surgery and even tattoo removal. But what exactly is a laser? There are numerous types, but all lasers work basically the same way. Learn how they generate such concentrated beams of light.

How do lasers work? | Who invented the laser? - Explain that Stuff
A laser differs from other sources of light in that it emits light that is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling uses such as optical communication, [6] laser cutting, and lithography.
The most powerful laser designed to date can be found at the European Extreme Light Infrastructure facility in Romania. Its lasers are some of the most intense in the world, generating insanely brief pulses of photons, protons, neutrons, and neutrinos with incredible energy.
Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.

A laser is created when electrons in the atoms in optical materials like glass, crystal, or gas absorb the energy from an electrical current or a light. That extra energy “excites” the electrons enough to move from a lower-energy orbit to a higher-energy orbit around the atom’s nucleus.

A laser is a device in which a collection of atoms or molecules, a semiconductor, or another quantum system, is held between mirrors and energized, or pumped, so that something in the system (the electrons, for example) reach a higher-energy "excited" state.\
Laser A telescope in the Very Large Telescope system producing four orange laser guide stars A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
A laser is the embodiment of curiosity disciplined into invention. It is proof that when humanity dares to ask questions and pushes the boundaries of possibility, we can shape even the light itself.
