Lasert
Lasert, often spelled laser, is an acronym for Light Amplification by Stimulated Emission of Radiation. It is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The emitted light is typically a narrow, focused beam of coherent light, meaning all the photons are in phase. This coherence allows lasers to have properties such as high intensity, monochromaticity (single wavelength), and directionality, which are not found in ordinary light sources.
The basic principle of laser operation involves three components: an energy source, a gain medium, and an
Lasers have found widespread applications across numerous fields. In industry, they are used for cutting, welding,
