In physics and engineering, surface power density or sometimes simply specific power is power per unit area.

While red laser diodes are commercially available, there are no commercially available green laser diodes which can provide the required power at room temperature with an adequate lifetime.

A krypton fluoride laser (KrF laser) is a particular type of excimer laser, which is sometimes (more correctly) called an exciplex laser.

Usually, laser ablation refers to removing material with a pulsed laser, but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough.

So this robot is actually equipped with a camera and a laser rangefinder, laser scanner.

(a) Boosting the production of equipment for the fuel and energy sector, including laser measuring systems, optoelectronic flame control systems, instruments to measure gas density, multiphase pumping plants and control systems for high performance gas pumping stations

For example, the first working laser was a ruby laser, made from ruby (chromium doped corundum).

The light from the high power IR laser diodes is converted into visible light by means of extra cavity waveguided second harmonic generation.

Female Voice Long range laser scanning by sending out a pulse that's a laser beam of light.

The Institute is a member of the International Laser Ranging Service (ILRS) and the European Laser Ranging Service.

Power The power available in a stream of water is formula_1where formula_2 power (J s or watts) formula_3 turbine efficiency formula_4 density of water (kg m³) formula_5 acceleration of gravity (9.81 m s²) formula_6 head (m).

Laser beam welding (LBW) is a welding technique used to join multiple pieces of metal through the use of a laser.

A random laser uses no optical cavity but the remaining principles of operation remain the same as for a conventional laser.

With advances in production, and commercial sales of low cost laser projectors, 445 nm InGaN laser diodes have dropped in price.

Nathan Myhrvold Could this laser zap malaria?

Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam.

Now, I put the laser here, and now, when I deal the cards in the laser, I know where they are but yes?

He showed it in Paris in 1867, and it was a major achievement because it brought the power density of the engine way up.

At this altitude, the air density is about 1 2200000 the density on the surface.

Laser hair removal has become popular because of its speed and efficacy, although some of the efficacy is dependent upon the skill and experience of the laser operator, and the choice and availability of different laser technologies used for the procedure.

Solid hydrogen has a density of 0.086 g cm3 making it one of the lowest density solids.

The first solid state laser, invented in 1960, was pumped by a xenon flash lamp, and lasers used to power inertial confinement fusion are also pumped by xenon flash lamps.

Most modern body composition laboratories today use the value of 1.1 kilograms per liter for the density of the fat free mass , a theoretical tissue composed of 72 water (density 0.993), 21 protein (density 1.340) and 7 mineral (density 3.000) by weight.

To ensure that the output of the beamlines is uniform, the initial laser light is amplified from a single source in the Injection Laser System (ILS).

The density of air, ρ (Greek rho) (air density), is the mass per unit volume of Earth's atmosphere.

Because so much of that book was a celebration of the power and creative potential of density, of largely urban density, of connecting people and putting them together in one place, and putting them on sidewalks together and having them share ideas and share physical space together.

A blue laser is a laser that emits electromagnetic radiation with a wavelength between 360 and 480 nanometres, which the human eye sees as blue or violet.

Next we can actually light them up with a laser.

In a laser, what makes laser light so different from the light above my head here is that this light is incoherent many different colors and different frequencies, sort of like the way you clapped initially but if you were a laser, it would be rhythmic applause.

If this energy is divided by the recording time in hours, it is then a density of power called irradiance, expressed in watts per square metre (W m2).

E Spaceship noise SW Even if it doesn't have a laser?

E Laser noise SW Yeah, yeah. That was pretty funny, Einstein.

(The two effects would cancel at a surface rock density of 4 3 times the average density of the whole earth.

Average density of 4.58 individuals per km2.

Population density is 43.3 inhabitants per km2.

Lasers In 1962, a group of researchers at Bell Laboratories discovered laser action in xenon, and later found that the laser gain was improved by adding helium to the lasing medium.

And so I started to think, well, you know, density, density I'm not sure if, you know, this was the right call.

445 nm blue laser diodes are currently available on the open market.

The population density was 17 km² (44 mi²).

The population density was 780 km² (2020.19 mi²).

Some areas have a low density of targets.

Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists.

The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed (invented by Kumar Patel of Bell Labs in 1964), and is still one of the most useful.

A Laser TV requires lasers in three distinct wavelengths red, green, and blue.
