arc-excited laser
1Laser 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… …
2Laser-induced breakdown spectroscopy — (LIBS) is a type of atomic emission spectroscopy which utilises a highly energetic laser pulse as the excitation source. LIBS can analyse any matter regardless of its physical state, be it solid, liquid or gas. Even slurries, aerosols, gels, and… …
3Laser beam welding — (LBW) is a welding technique used to join multiple pieces of metal through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. The process is frequently used in high volume… …
4Laser 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… …
5Ultra fast laser spectroscopy — is the study of molecules on extremely short time scales (nanoseconds to femtoseconds) after their excitation with a pulsed laser. This method is used extensively to examine the energy states and electron dynamics of any molecule whose reaction… …
6TEA laser — The CO2 TEA laser was invented in the late 1960s by Dr Jacques Beaulieu working at the Defence Research Establishment, Valcartier, in Quebec, Canada. The development was kept secret until 1970 when brief details were published.C K N Patel,… …
7Nitrogen 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… …
8Différents types de laser — Liste des différents types de laser Ceci est une liste des différents types de lasers avec la longueur d onde sur laquelle ils opèrent et leurs applications. Il existe plusieurs milliers de sortes de lasers mais la plupart d entre eux ne sont… …
9Liste des différents types de laser — Ceci est une liste des différents types de lasers avec la longueur d onde sur laquelle ils opèrent et leurs applications. Il existe plusieurs milliers de sortes de lasers mais la plupart d entre eux ne sont utilisés que dans le cadre de… …
10Solid-state laser — A solid state laser is a laser that uses a gain medium that is a solid, rather than a liquid such as in dye lasers or a gas as in gas lasers. Semiconductor based lasers are also in the solid state, but are generally considered as a separate class …
