pumping Dictionary Terms

image enhancement laser
A semiconductor platelet laser that emits a coherent image by means of plane optical pumping over the platelet surface, and...
gas laser
One of the first lasers to find practical application. Generally, the pumping mechanism is an electric discharge, although...
transverse pumping
The laser pumping that exhibits an advantage over longitudinal pumping in that the threshold pump power density can be...
xenon flashtube
A high-intensity source of incoherent white light in which a capacitor is discharged through a tube of xenon gas; often used...
q-switched operation
Q-switched operation, or q-switching, is a technique used in lasers to produce short and intense pulses of light. The term...
far-infrared laser
A laser with output over a wide range of wavelengths spanning the far-infrared region of the spectrum (30 to 1000 µm);...
diode laser
A diode laser is a type of laser that uses a semiconductor diode as the active medium to generate coherent light....
diode-pumped solid-state laser
A diode-pumped solid-state laser (DPSSL) is a type of laser system that uses semiconductor diode lasers to pump energy into...
optically pumped laser
A laser in which stimulated emission is triggered by the absorption by electrons of light from an auxiliary source such as a...
optical pumping
The process whereby the number of atoms or atomic systems in a set of energy levels is changed by the absorption of light...
photopumping
The use of light to initiate the lasing process. See optical pumping.
hair-trigger operation
Triggering a laser at a predetermined time by pumping it to a level just below its threshold and then using an auxiliary...
collinear pumping
A method of exciting a laser by coupling it directly to another laser.
chemical laser
A laser that relies on chemical activity instead of electrical energy to produce the pumping action necessary to form pulses...
ultrashort-pulse laser
A laser capable of generating light pulses that last only a few femtoseconds. This can be achieved by nonlinear filtering to...
pumping band
A group of energy levels to which ions in the ground state are initially excited when pumping radiation is applied to a...
bakeout
The elimination of gases from the surfaces of a vacuum system by heating the surfaces when the pumping phase is occurring.
mode hopping
Mode hopping in the context of lasers refers to a phenomenon where a laser system abruptly switches from one longitudinal...
longitudinal pumping
A dye laser cell configuration in which the dye flows in the direction of the axis of the laser, yielding symmetrical energy...
pumping radiation
Radiation used to excite an optical or laser material to a higher energy level. See optical pumping.
excited-state absorption
In laser pumping, parasitic absorption that occurs at certain wavelengths, decreasing pump efficiency and gain.
Nd:YAG laser
Nd:YAG laser refers to a solid-state laser that utilizes neodymium-doped yttrium aluminum garnet (Nd:Y3Al5O12) as the gain...
dye laser
A laser using a dye solution as its active medium. Its output is a short pulse of broad spectral content and its achievable...
synchronous pumping
The technique of generating ultrashort -- down to subpicosecond -- pulses by pumping a dye laser with mode-locked laser...
