How Much Feet Does A Sight Laswr Travel?

by | Last updated on January 24, 2024

, , , ,

Each laser has the power of about four laser pointers and must be detected by a spacecraft an average of

137 miles (220 kilometers)

away. Even the ultra- precise assembly of the satellites isn't enough to guarantee the laser transmitted from each spacecraft will be aligned well enough to hit the other spacecraft.

What is the range of laser light?

Color Wavelength(s)
Red


638 nm, 650 nm, 670 nm
Orange 593 nm Yellow 589 nm, 593 nm Green 532 nm, 515/520 nm

How far can a 1mw laser go?

The 1 mW red pointer has a glare distance of

255 feet

, compared to the same power green laser, which can cause glare at 490 feet.

Can a laser hit the moon?

The typical red laser pointer is about 5 milliwatts, and

a good one has a tight enough beam to actually hit the Moon

—though it'd be spread out over a large fraction of the surface when it got there. The atmosphere would distort the beam a bit, and absorb some of it, but most of the light would make it.

Do lasers go on forever?

A:

The light from a laser in space would continue on forever unless it hit something

. However, if you were far enough away, you wouldn't be able to detect the light. A projectile would also continue on forever unless it hit something.

How far can a 1000mw green laser go?

Factors like cloud coverage, fog, and if you're at a high point of elevation should be considered, but as a basic rule, you can expect

over 10 miles

of visible distance on green 200mW+ lasers and 1,000mW+ blue lasers.

Does gravity affect a laser?

Really big curvature of light by gravity occurs near the strange objects called black holes, which were also predicted by General Relativity. So

yes, the light ray from your laser will technically be bent by the earth's gravity

.

Can a laser pointer reach an airplane?


You should NEVER aim a laser pointer at or near an airplane, helicopter or drone

(drones are legally considered aircraft and you may blind or damage the operator's camera). It is not safe, you may be arrested, and you may help get laser pointers banned.

Is laser 303 illegal?

And yes, lasers above 5 mW are commercially available in the United States, but

it is illegal to market them as Class IIIa devices

. Some units in the NIST study tested as high as 13 times over the legal limit at 66.5 mW.

Is it illegal to shine a laser pointer into the sky?

While pointing a laser at a helicopter or plane may seem harmless, the opposite is true. It's dangerous—both to those in the air and on the ground—and

it's a federal crime

.

What color laser is the strongest?

As a general rule,



are 532nm are 5-7X brighter than any other laser color, at the same power. Whether blue, red, purple/violet, or a light color like yellow, green is the best at strength for visibility.

Is 1mW or 5mW more powerful?

The advantage of the 1mW is:

it is more power-effective than the 5mW version

. So it could be used for a longer time than the 5mW version.

How far can a 10000 MW laser go?

Just gently press the switch button; you will notice a beam of strong green light sending out from the laser pen. With such a portable tool, you can point at any target as far as

5000 meters

.

What is a 303 laser?

Can a laser pointer start a fire?

What happens if you stare into a laser?

The human eye is extremely sensitive to laser radiation.

Stronger laser exposure can cause severe permanent vision loss

. Laser pointer beams can cause visual loss which may not be permanent but can last for months. The treatment for laser retinal injuries is very limited, so prevention is key.

What happens if two lasers collide?

Actually, when two laser beams (or any other kinds of light for that matter) collide,

they do not stop each other

. In fact, usually they behave as though the other is not there at all. This is because light is a wave, and usually waves cross each other without interacting.

What is the strongest laser?

  • The Thales system has generated its first pulses at a world record power level of 10 petawatts.
  • ELI-NP now has the world's most powerful laser system.

How fast do laser beams travel?

One of the most sacred laws of physics is that nothing can travel faster than the speed of light in vacuum. But this speed limit has been smashed in a recent experiment in which a laser pulse travels at

more than 300 times the speed of light

(L J Wang et al. 2000 Nature 406 277).

Do lasers stop?


Light from a laser does not stop in mid-air, but continues going

. A pilot at the other end can clearly see the light from even a relatively low powered 5 mW green laser, at a distance well over 2 miles.

How far can the 303 laser go?

Harupink 303 Laser Pointer Pen

10 Miles

Military Focus Laser Torch 532nm 1 MW, Green.

How far can a 5 MW laser go?

The diagram below shows the hazard distances for a 5 milliwatt “U.S. legal” green laser pointer with a 1 milliradian beam divergence: It is a potential eye hazard from the pointer to about

52 feet

. It is a temporary flashblindness hazard from the pointer, out to about 260 feet.

What is a Class 5 laser?

Class 5 Photonics delivers

ultrafast, high-power laser technology at outstanding performance to advance demanding applications from bio-imaging to ultrafast material science and attosecond science

.

Can laser bend space?

Photons, whether from a laser or not,

do not curve space

. Rather they follow curved paths when they are in the proximity of large masses such as stars. Laser beams do not curve spacetime. Not because they aren't powerful enough, but because that isn't what EM does to spacetime.

Can laser bend space time?


Yes, photons bend spacetime

.

Do lasers work in space?


One of the most common uses of lasers in space is for environmental and remote sensing

. In this application, a laser stationed on a satellite can orbit Earth (or other heavenly bodies such as the Moon or Mars) and direct a sequence of short optical pulses onto the surface.
