Gain-switching — is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, of the order of picoseconds (10 12s).In a semiconductor laser, the optical pulses are generated by injecting a large number of carriers… … Wikipedia
Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… … Wikipedia
Gain (lasers) — Gain (or amplification) in laser physics is a process, where the medium transfers part of its energy to the emitted electromagnetic radiation, resulting in an increase in laser power. This is basic principle of all lasers.Quantitatively, the… … Wikipedia
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 the number of particles in one excited state exceeds the number of particles… … Wikipedia

Laser construction — A laser is constructed from three principal parts:*An energy source (usually referred to as the pump or pump source ), *A gain medium or laser medium , and *Two or more mirrors that form an optical resonator . Pump sourceThe pump source is the… … Wikipedia
Laser diode — Top: a packaged laser diode shown with a penny for scale. Bottom: the laser diode chip is removed from the above package and placed on the eye of a needle for scale … Wikipedia
Gain — For other uses, see Gain (disambiguation). In electronics, gain is a measure of the ability of a circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output. It is usually defined as the mean ratio of… … Wikipedia
Nitrogen laser — A 337nm wavelength and 170 µJ pulse energy 20 Hz cartridge nitrogen laser A nitrogen laser is a gas laser operating in the ultraviolet range[1] (typically 337.1 nm) using molecular nitrogen as its gain medium, pumped by an electrical… … Wikipedia
Quantum cascade laser — Quantum cascade lasers (QCLs) are semiconductor lasers that emit in the mid to far infrared portion of the electromagnetic spectrum and were first demonstrated by Jerome Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson,… … Wikipedia
Diode-pumped solid-state laser — A frequency doubled green laser pointer, showing internal construction. Cells and electronics lead to a laser head module (see lower diagram) This contains a powerful 808 nm IR diode laser that pumps a Nd:YVO4 laser crystal, that in turn outputs… … Wikipedia
