How far can a 1000mW green laser go?

Output power ( mw ) – A 200mW laser will be visible for more than 1 miles while a 1000mW laser pointer or more will also be visible for 10 miles.

Are pointer lasers illegal?

In the U.S., it is legal under federal law to own a laser of any power. But often people talk about “illegal laser pointers”. This is somewhat confusing shorthand meaning that the manufacturer or seller illegally called a laser above 5 milliwatts a “pointer”, or illegally promoted it for pointing purposes.

What is considered a powerful laser pointer?

Visible laser pointers (400–700 nm) operating at less than 1 mW power are Class 2 or II, and visible laser pointers operating with 1–5 mW power are Class 3A or IIIa. Class 3B or IIIb lasers generate between mW; Class 4 or IV lasers generate more than 500 mW.

Could a laser pointer reach 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.

Is it illegal to shine a laser at the moon?

Alas, the answer is no. Such a laser beam is too weak and too small to travel through sixty miles of earth atmosphere and then traverse 238,000 miles of open space before it strikes the moon.

Are beams on guns illegal?

The FDA restricts the output power of visible lasers that can be sold to “civilians” to no more than 5 milliwatts (mW) and classifies lasers we are allowed to buy for firearms as Class IIIA. ... The interpretation of the intent seems to be for a responsible safety purpose to remind shooters of the laser danger.

Why are green lasers illegal?

The primary culprit was overpowered units. The Code of Federal Regulations in the United States limits commercial class IIIa lasers to 5 milliwatts (mW). And yes, lasers above 5 mW are commercially available in the United States, but it is illegal to market them as Class IIIa devices.

How far can a 5 mW laser go?

A 5 milliwatt laser: a distraction 2 miles away 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 does 5 mW mean?

Definition. 5MW. Five Minute Warning (Freenet)

Can a telescope see the flag on the moon?

Can you see an American flag on the moon with a telescope? Even the powerful Hubble Space Telescope isn't strong enough to capture pictures of the flags on the moon. But the Lunar Reconnaissance Orbiter, the unmanned spacecraft launched in 2009, is equipped with cameras to photograph the moon's surface.

Can a laser destroy a mirror?

A laser certainly can burn through a mirror. I have burned through a few mirrors with lasers, or at least I have had mirrors burned through. I tried my best to keep it from happening. My job was to get the laser beam reflected by the mirror without damage.
