Lasers produce a highly focused beam of radiation. This effect is based on the theory of controlled output of photons. The fundamental parts of a laser system contain an active medium, a pump source, and optical resonators. The active medium is activated by the pump source, causing particles to transition to higher energy levels. Upon returning to their ground state, these atoms emit photons that are strengthened within the resonators, resulting in a coherent and monochromatic beam of light.
