A laser beam (which is shot through a ruby or gas to make it so fine)
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.

A laser
Focusing light into a narrow beam increases its intensity, allowing for more precise illumination. This can be beneficial in applications such as laser cutting, microscopy, and fiber optic communications where concentrated light is required. It also helps to reduce light dispersion and increase the range of the light beam.
is coherent, monochromatic, and concentrated in a narrow beam.
A laser
a small laser, or a laser pointer
A laser (light amplification by stimulated emission of radiation) is a device that produces a narrow beam of coherent light by amplifying light through a process called stimulated emission. This beam of laser light can be focused to a very small spot and is used in various applications ranging from scientific research to medical procedures.
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.
