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 does laser beam mean?
A laser is the device itself, the beam is.. well, the beam coming out of the laser.
In a vacuum space the red laser beam travels faster then the beam of microwaves true or false?
Both beams travel at the same speed.
Can sound waves travel through lasers?
Yes. The laser beam is a beam of coherent light. Just photons. Meanwhile the sound wave is travelling through a medium....which isn't really true of the photons, they'll travel whether there's a medium or not. There's essentially no interaction or interference between the two. Saying that I can think of ways you could detect sound waves using lasers...but I wouldn't worry about that - sound will travel just fine through a laser beam providing it still has a medium to travel through. i.e: a laser can be present in a strong vacuum but sound won't pass through a strong vacuum - at least not to any useful degree....but that's not the laser stopping it.
How does a laser beam garage door work?
A laser beam garage door opener works when the beam is broken by a vehicle or an opener is activated. The activator opens the door.
What is an amplified light beam?
laser
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.
In a vacuum space the red laser beam travels faster then the beam of microwaves true or false?
Both beams travel at the same speed.
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?
"Caution Laser Beam" is a phrase used on warning signs and labels to alert users and passersby that a laser beam may be present.
In a laser printer the beam detect mirror detects the laser beam by reflecting it to a blank?
optical fiber
What is a laser modulator used for?
A laser modulator is used to change modulate a beam of light (or laser). The easiest way that they modulate the laser, or light beam, is by changing the rate at which the laser is emitted from the source.
How far does a 100mW laser go?
Some can travel over 25 miles.
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.
