Abstract

So far we have discussed the physics behind laser operation. Basically the light from both a laser and any ordinary source of light is electromagnetic in nature, but laser light can be extremely monochromatic, highly directional, and very intense. Apart from these laser light also differs from light produced by thermal emission in the basic quantum properties.
