Abstract: LASER (Light Amplification through Stimulated Emission of Radiation) is one of the most outstanding inventions of the 20th century. In contrast to common light sources, which emit incoherent photons at many frequencies, lasers generate coherent radiation at many wavelengths ranging from meter wavelength region to the soft X-rays region. Laser technology touches almost every aspects of daily life in the 21st century. Due to remarkable features of lasers such as directionality, coherences, monochromaticity and high intensity; they are used in a wide variety of applications in all walks of life starting with communications to medicine. This article covers a general overview of ‘LASERS’ and its current applications.
