It depends on what colour it is, the type of laser it is, the output level, the quality of the optics and the media it's travelling through. In a perfect vacuum, they'll travel much longer than through atmosphere.
For example, green lasers travel further than red or blue. Class 1 and 2 lasers have an output power level of <5mW. Class 3 can go up to 100mW. See related link.
What else can I help you with?
How fast does a laser beam travel in a mile?
A laser beam travels at the speed of light, which is approximately 186,282 miles per second.
What is the angular spread of the light emitted by a laser beam?
The angular spread of light emitted by a laser beam refers to the width of the beam as it diverges from its source. It is typically very narrow, with a small angular spread, allowing the light to travel in a focused direction.
What does laser beam mean?
A laser beam is a narrow, focused, and intense beam of light produced by a device called a laser. Laser beams are used in various applications such as cutting, welding, medical procedures, and communication systems due to their ability to deliver high energy in a precise manner.
Is laser light is parallel beam of light?
Yes, laser light is often described as a parallel beam of light because the photons in laser light travel in a very tightly focused and uniform direction, unlike conventional light sources which emit light in multiple directions. This property of laser light allows it to be easily focused into a narrow beam with minimal divergence.
How can one see an invisible laser beam?
One can see an invisible laser beam by using special equipment like a laser beam detector or by observing the beam's reflection off of particles in the air.

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.
How can you get laser?
How can yo u get laser beam?What is laser beam characteristics and principles?
How does the laser ranging device work?
A laser-rang device works by using a laser beam to find horizontal fault movements. It can also use the laser beam to travel to a reflector and then back. Thus, the device can detect any change in distance to the reflector.
What is the angular spread of the light emitted by a laser beam?
The angular spread of light emitted by a laser beam refers to the width of the beam as it diverges from its source. It is typically very narrow, with a small angular spread, allowing the light to travel in a focused direction.
If it takes 5 seconds for a laser beam to strike an object in space how far would that object be?
Light travels at 186600 mps in vacuo. This means that in 5 seconds the light from a laser would travel 186600 * 5= 933000 miles away/

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 is caution laser beam?
A caution laser beam is a warning sign used to indicate the presence of a laser that may be harmful to the eyes or skin. It alerts individuals to use proper protection and avoid direct exposure to the laser beam.
How can one see an invisible laser beam?
One can see an invisible laser beam by using special equipment like a laser beam detector or by observing the beam's reflection off of particles in the air.
Can a mirror effectively reflect a laser beam?
Yes, a mirror can effectively reflect a laser beam.
