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

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.

It employs a technique known as collinear holography, whereby a green and red laser beam are collimated in a single beam.

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

The range finder mounted on the top is a Velodyne 64 beam laser.

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

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.

Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam.

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

The Fresnel lens is useful in the making of motion pictures not only because of its ability to focus the beam brighter than a typical lens, but also because the light is a relatively consistent intensity across the entire width of the beam of light.

Each year, between October 9 and December 8, it projects a vertical beam of light high into the sky.

When the wavefront passes through them, the amplifiers release some of the light energy stored in them into the beam.

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

To determine blood glucose, the measuring beam of infrared light, for example, has to penetrate the tissue for measurement of blood glucose.

On the Democratic side, the same sorts of hacks and PR men focused like a laser beam on the bad employment news of the George W. Bush years, ignoring the good news about output and productivity.

You can't see light. When it's dark, in a vacuum, if a person shines a beam of light straight across your eyes, you won't see it. Slightly technical, some physicists will disagree with this.

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

There's an infrared beam that's going across, and he has stepped into the beam and taken his photograph.

And if I don't need it, I can convert it back up on the window to energy, light, and beam it, line of site, to your place.

Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti sapphire laser.

Laser does not work well on light colored hair, red hair, grey hair, white hair, as well as fine hair of any color, such as vellus.

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

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

A major part of Bethlehem Steel's success was the development of the H beam, a precursor of today's ubiquitous I beam.

In this machine, a beam of protons and anti protons are accelerated to near the speed of light and brought together in a collision, producing a burst of pure energy.

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?

Electron beam welding (EBW) is a fusion welding process in which a beam of high velocity electrons is applied to two materials to be joined.

Studies on the light emitted by laser trapped francium 210 ions have provided accurate data on transitions between atomic energy levels which are fairly similar to those predicted by quantum theory.

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

So this animation just tries to explain this concept where we made these cells sensitive to being turned off with light, and we beam light in, and just for the time it takes to shut down a seizure, we're hoping to be able to turn it off.

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.

This oh sorry, don't look at the beam. My fault.

These lasers combine high overall efficiency with good beam quality.

Some faces , that Day , will beam ( in brightness and beauty )

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.

This utilises a property of and other materials specifically that a thin layer of gold on a high refractive index glass surface can absorb laser light, producing electron waves (surface plasmons) on the gold surface.

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.

Plasma applications Particle beams File Nasa Shuttle Test Using Electron Beam full.jpg_right_thumb_alt A violet beam from above produces a blue glow about a Space shuttle model_During a NASA wind tunnel test, a model of the Space Shuttle is targeted by a beam of electrons, simulating the effect of ionizing gases during re entry.
