How long would it take a laser beam to hit mars from earth orbit?

It depends on where Earth and Mars are in their orbits. Since Mars takes longer to orbit the sun than Earth does the distance between the two planets varies considerably. When Earth and Mars are closest a beam of light will take about 4 minutes to reach Mars from Earth. When they are farthest (on opposite sides of the sun) a bean of light would take about 12 minutes.

What is caution laser beam?
"Caution Laser Beam" is a phrase used on warning signs and labels to alert users and passersby that a laser beam may be present.
Laser beam needs electricity or not?
All lasers require electricity to operate. The laser beam that results from operation of a laser is electromagnetic radidation, not electricity.
Can a laser beam blow a hole through titanium?
In certain circumstances, a laser beam can potentially blow a hole through titanium. The effectiveness of the laser depends on its power, focus, and duration of exposure to the material. However, it is worth noting that titanium is a strong and durable metal, so it would require a powerful and focused laser beam to achieve this outcome.
Why laser produces Gaussian beam?
A laser produces a Gaussian beam because of the diffraction effect of the laser beam passing through an aperture. The electric field distribution of the beam follows a Gaussian shape due to the wave nature of light. This results in a beam that has a bell-shaped intensity profile with a narrower central peak and gradually decreasing intensity towards the edges.
How long would it take a laser beam to go from earth to Sirius?
Since sirius is 8.6 light years away and light travels at the speed of light including lasers then guess what?? It's gonna take 8.6 years...
Can laser light reached at moon and can reflect back?
Yes. The moon's high albedo is used as a mirror to reflect laser light from the Earth. They more accurately track the orbit and distance of the moon than previous methods. However, in order to have a reflected laser beam that the eye could see (like in a movie) the laser would have to be incredibly strong and have a large beam. No laser currently on Earth is capable of this. However, the moon's albedo is high enough that if such a significantly large laser existed it could reach the moon and be reflected back.
How far away would a beam of light have to be to be able to watch it travel?
This would not be possible for a couple of reasons. First let us set up the following scenario. We will shoot a laser from the Earth to the Moon which will take 1.2 seconds to arrive. You will be observing from 240,000 miles away in a spaceship that is at a right angle to the laser beam. This will make the Moon the same apparent size as it is on Earth. In theory, you should see a laser beam begin from Earth and quickly get longer and longer until it reaches the Moon in 1.2 seconds. The problem is that when we see a laser beam, we are not actually seeing the beam itself, only a small part of the beam reflecting off particles in the laser beam's path. Since space is a vacuum, there are no particles for the beam to reflect off, so we see nothing unless the laser beam is pointed directly at us, which in this case is not. The other problem is that when the laser light is reflected toward us from the particles, it is also scattered and would be much too faint to observe from that distance, even with a telescope.
What does laser beam mean?
A laser is the device itself, the beam is.. well, the beam coming out of the laser.
Is a laser beam the straightest thing on earth?
Not nessacary. It can also be a fine stick, or a piece of wood. But it can be among the straightest. This is because a laser beam somewhere will emit light.
How can you get laser?

What is the name of the beam of light used to measure the distance from earth to moon?
Laser
can a laser beam hit the moon from earth?
No, not from the earth. The pointers are not precise enough to keep the peam at that distance. In addition, the dust particles in the atmosphere would scatter the beam before it got there.
Can you put a LED inside a laser housing to focus it into a beam just like a laser diode would?
No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing. A laser produces coherent light, which is why it acts like a beam. A normal LED is not coherent, and you can not make it so. Although you can not make a collimated incoherent light beam able to travel similar distances as a collimated laser beam, you can collimate incoherent light into a beam which would travel some distance with a small amount of divergence.
