The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. [ 1 ][ 2 ] The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. [ 1 ] Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of ...

Laser using an optical fiber as the active gain medium. A fiber laser(or fibre laserin Commonwealth English) is a laserin which the active gain mediumis an optical fiberdoped with rare-earth elementssuch as erbium, ytterbium, neodymium, dysprosium, praseodymium, thuliumand holmium. They are related to doped fiber amplifiers, which provide light ...
The photo on the right shows the head assembled. Laser pumping is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms. When for a period of time the number of particles in one excited state exceeds the number of particles in the ground ...
An optical cavity, resonating cavity or optical resonator is an arrangement of mirrors or other optical elements that confines and amplifies (resonance) the light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric oscillators ...
Laser linewidth from high-power high-gain pulsed laser oscillators, comprising line narrowing optics, is a function of the geometrical and dispersive features of the laser cavity. [29] To a first approximation the laser linewidth, in an optimized cavity, is directly proportional to the beam divergence of the emission multiplied by the inverse ...
Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
