A laser pulse is fired (Music)

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

But for a wave pulse its pretty easy to see where the wave is so, now that we know where the pulse is what's it frequency?

Well, a localized pulse doesn't really wave so we can't measure the frequency of its crest.

Now, this is a low powered laser, and we can actually pick up a wing beat frequency.

This is high frequency laser, and it's enough with a fraction of a second to destroy the retina completely.

This mechanism should also ban sending into outer space not only conventional arms, but also laser, high frequency or anti satellite weapons.

So you can change the intensity, the frequency, the duration, the pulse shape of the ultrasound to create anything from an airbrush to a hammer.

Among the inter cavity doubled lasers VCSELs have shown much promise and potential to be the basis for a mass produced frequency doubled laser.

Laser

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

Appearance The violet 405 nm laser (whether constructed from GaN or frequency doubled GaAs laser diodes) is not in fact blue, but appears to the eye as violet, a color for which a human eye has a very limited sensitivity.

What's the pulse?

How's her pulse?

Good femoral pulse.

Laser pulses with about 10 kHz repetition rate and various lengths are sent to a Digital Micromirror Device where each mirror directs the pulse either onto screen or into the dump.

And if you can cause that coil to resonate, what will happen is it will pulse at alternating current frequencies at a fairly high frequency, by the way.

And we're going to show you, instead of the kill laser, which will be a very brief, instantaneous pulse, we're going to have a green laser pointer that's going to stay on the mosquito for, actually, quite a long period of time otherwise, you can't see it very well.

I feel the pulse.

She has no pulse.

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.

The doctor took his pulse.

The pulse varies with age.

His pulse is very weak.

The pulse is very bad.

A second pulse ended this activity.

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