Understanding Lasers: Foundations and Implementations
Lasers produce a highly focused beam of energy. This occurrence is based on the principle of induced output of photons. The fundamental elements of a laser system contain an active medium, a pump source, and optical resonators. The active medium is activated by the pump source, causing molecules to transition to higher energy levels. Upon returning to their ground state, these atoms release photons that are intensified within the resonators, resulting in a coherent and monochromatic beam of light.
Laser implementations span a wide range of fields. In communications, lasers are used for optical fiber communication. In surgery, lasers are employed for precise removal of tissues. Industrial applications include laser marking, fusion, and material processing.
