The concept of laser light is better understood by the definition of its properties.
Laser light has three properties: monochromatic, coherent, and collimated. When
all emitted photons bear constant phase relationship with each other in both time
and phase the light is said to be coherent. It is also monochromatic (one color)
due to the specificity and purity of the medium used. Last, the light is contained in
a very narrow pencil, almost collimated (reference
Figure 3
).
