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.

What is the difference between a ray of light and a beam of light?
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
What is a device that produces a narrow beam of coherent light?
A Laser.
What is an intense beam of light?
In an exam they would look for: (very) bright
What is the definition of ray in physics?
I think it's one of these a straight narrow beam of light from the sun or moon a beam of heat, electricity, or other form of energy
Why do laser emit such intense light?
The beam from a LASER light is all the same frequency. It disperses slowly making it very powerful. Coherent light.
What sends a narrow intense beam of light?
a small laser, or a laser pointer
A thin beam of light is?
A ray is a narrow beam of light.

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.
What is light beam?
a narrow projection of light energy radiating from a sourse into a beam

How is night blindness diagnosed?
A slit lamp examination, in which a narrow beam of intense light is used to examine the internal components of the eye, may also be performed. Additional testing may be performed
