How far can a red laser travel?

Around 100 meters away from a red laser pointer, its beam is about 100 times wider and looks as bright as a 100-watt light bulb from 3 feet away. Viewed from an airplane 40,000 feet in the air -- assuming there's no clouds or smog -- the pointer would be as bright as a quarter moon.

How far can the longest laser go?

Researchers have demonstrated the longest laser ever built, using an optical fiber that could stretch from Washington, DC, to Baltimore. In the 20 January PRL, a team shows that their 75-kilometer laser can transmit light signals with hardly any loss of power over that distance.

Can my laser 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.

Can a laser destroy a mirror?

Ryan Hoffman, Counter-Directed Energy program manager, says that mirrors protect well against low-power lasers. “However, reflective surfaces are not 100 percent reflective,” he says. “The small amount of laser energy that's absorbed will heat the mirror and cause damage.”

Can a laser reach Mars?

Engineers from Canada claim that a laser-based system to reach Mars could tremendously cut the time it takes to reach the Red Planet. According to NASA's estimates, it would take about 500 days for humans to reach Mars at current speeds.

How far can a blue laser go?

Green at 532 nm vs.

Here is a comparison of two 1 watt handheld lasers. One is green at 532 nm (88% apparent brightness) and the other is blue at 445 nm (3% apparent brightness). The green has a visual hazard distance of 25.5 NM, while the exact same laser in blue has a visual hazard distance of only 4.8 NM.

How far can a green laser go?

This green laser pointer has a reported range of 80 km (50 miles.) The laser is easily visible in the day time too, well over 30 meters (100 feet,) — and likely even more — even in bright daylight, I discovered (see image at the bottom.) SKYlaser laser pointers are about the size of a Sharpie pen.

Can a laser go on forever?

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. Lasers produce light that can be tightly focused.

Is green laser safer than red?

Green is more easily perceived by the eye and the beam is visible along its path. But green lasers are also more dangerous. Green is more easily absorbed by the retina than red, so it requires less exposure to cause damage.
