In reality, emissions are often much lower than the "potential to emit.
Finally, if you're in an "Extreme" air-pollution area, you're a "major" polluter if you emit only 10 TPY, but you have 20 years to comply.
For any given temperature and wavelength, it specifies exactly how much radiation an idealized thermal source known as a black body will emit.
When excited by laser beams entering from outside the cavity, the atom initially emits photons randomly.
By varying the thickness of the layers, it is possible to select the particular wavelength at which a QC laser will emit light, allowing scientists to custom design a laser.
The stack emits a laser beam because many electrons forced into those wells by the high voltage carry more energy than the wells can accept.
At the heart of the novel, almost entirely plastic device is a material called poly(p-phenylenevinylene), or PPV, which emits green light when stimulated with electricity (SN: 8/24/96, p.
In an invited lecture, Bell Labs physicist Claire Gmachl will describe the world's first quantum cascade laser that emits light continuously and reliably over a broad spectrum of infrared wavelengths.
If a critical number of photon circuits arises in a patch of grainy film, it emits laser light.
Each device emits light so that the sandwich generates more light with the same current flow than would be generated by a single device.
Gas pulled toward these superdense objects forms a disk around them, and as material in the disk gets compressed and heated, it emits X rays.
Scientists at Bell Labs, the research and development arm of Lucent Technologies (NYSE:LU), have built a semiconductor laser that emits light in the far reaches of the infrared spectrum, a region where it is notoriously difficult to get lasers to work.
Some of the earliest bind iodine-131, an isotope that emits low-energy gamma radiation along with a beta particle.
Forrest, Professor of Electrical Engineering at Princeton University, at the International Symposium on Functional Dyes in Osaka, Japan, this record-breaking device employs a new iridium-based dopant molecule that emits light based on the mechanism of OLED electrophosphorescence.
The measurements reveal a specific relationship between the spin of a black hole and the energy it emits as gas is pulled from an orbiting companion onto a disk of material that surrounds and feeds the hole.
