Power applied to laser, wavelength & angle of viewing it.
You can see the beam from a laser if there are particles or dust in the air that scatter the light, making the beam visible. Another way is to use special equipment like fog or smoke machines to make the beam more visible. Additionally, some lasers are designed with a visible light wavelength that is more easily seen by the human eye.

Why cant you see a laser beam as it crosses the room?
You can't see a laser beam crossing a room because the laser produces a narrow, focused beam of light that is not scattered easily. The light particles in the laser beam are not interacting with the air particles in the room, so there are no particles for the light to bounce off of and become visible to the human eye.
Why do you see the laser beam from powder?
When a laser beam hits a powder, it scatters the light in all directions due to the irregularities and rough surfaces of the powder particles. This scattering effect causes the laser beam to become visible as it interacts with the particles, making it appear as though the beam is "visible."
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.
Why cant you see a laser beam if its in pure water?
You can't see a laser beam in pure water because the water is transparent, which allows the light to pass through without scattering. This means that the laser beam doesn't interact with the water molecules in a way that makes it visible to the human eye.
How can we see a lazer beam?
A laser beam is usually invisible to the naked eye. However, if there are particles or dust in the air, the beam may scatter the light and become visible as a thin line. Another way to see a laser beam is to use special goggles or a camera that can detect the specific wavelength of the laser.

Why can you see a light from a laser beam?
If you see the beam, you are seeing the scattered light being reflected off particles in the air. Any light you actually see is no longer laser light, assuming you have sense enough not to look at it directly.

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 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 unit is the power of a laser beam?
The power of a laser beam is typically measured in watts (W). This measurement indicates how much energy the laser beam is emitting per unit of time.
Why can't I see my laser pointer beam anymore?
Dead battery OR very clean air.
In a laser printer the beam detect mirror detects the laser beam by reflecting it to a blank?
optical fiber
