That's one of the properties necessary to consider a source of light as a laser source.The light rays in a laser are manipulated so as to make them coherent.

Are all of Samus Aran's beam weapons technically lasers?
No. A laser is a device that emits a narrow but intense beam of light. Samus' beam weapons have a variety of effects that could not be explained by lasers.
A laser produces light that is what?
Intensified.
How is laser light different from incandescent light?
The intensity of light from most light sources is inversely proportional to the square of the distance from the source. So the intensity two meters from an incandescent lamp is one quarter of the intensity at one meter, and at three meters from the lamp the intensity is one ninth of the intensity at one meter. Laser light ideally has the same intensity at any distance.
Why is the laser beam made of a light of a single colour?
The color of a beam of light is dependent on its wavelength. A laser will appear as one color because all the light being emitted from it is the same wavelength. This is also why lasers and laser pointers always have such a tight beam. By contrast, flashlights (which have much wider beams, and rely on mirrored interiors to amplify the light) have light at a variety of wavelengths, which is why the light is ultimately "colorless".
Why does laser light visible in smoke?
yes,you should be able to...i think why dont you test it?
What sends a narrow intense beam of light?
a small laser, or a laser pointer
What is a device that produces a narrow beam of coherent light?
A Laser.
A narrow beam of light that travels in a straight line is a?
A laser
Why laser moves in narrow parallel beam of light?
Because a laser is just concentrated light, so it is thin from being concentrated.
What is the name of a narrow beam of light used to cut drill or slice?
A laser
What is the narrow beam of light?
A laser beam (which is shot through a ruby or gas to make it so fine)
What makes up laser light and how is it used?
Laser light is different from ordinary light. Laser light consists of light waves that all have the same wavelength, or color. The waves are coherent, or in step. A laser is a device that produces a narrow beam of coherent light. The word laser comes from a phrase that describes how it works: light amplification by stimulated emission of radiation. Light amplification means that the light is strengthened. Stimulated emission means that the atoms emit light when exposed to electromagnetic radiation.
What sends out a narrow intense beam of light?
Well... Most LEDs, Light Emitting Diodes, have a very narrow wavelength span, so they'd fit part of your question. However, they're not always that intense. So you're probably asking about a LASER.
Difference between normal light and laser light ray?
white light is the full visible like spectrum. lasers are monochromatic. a single or very narrow frequency or wavelength.
What is a laser light with holograph?
a laser light with a holograph is a laser light with holograph.
How does laser paint work?
Laser paint contains a phosphorescent pigment. When UV or light falls on the pigment the energy is stored and released again over time, causing the 'glow'. The laser emits the energy, and it does so in an extremely narrow beam, making it possible to 'write' with it.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
