Lasers produce a highly focused beam of light. This phenomenon is based on the principle of stimulated release of photons. The fundamental components of a laser system comprise an active medium, a pump source, and optical resonators. The active medium is excited by the pump source, causing atoms 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 uses span a extensive range of fields. In telecommunications, lasers are used for optical fiber communication. In surgery, lasers are employed for precise treatment of tissues. Industrial applications include laser etching, joining, and manufacture. Furthermore, lasers play a crucial role in scientific research across diverse areas such as spectroscopy, holography, and quantum optics.
