lézerfényforrást

Lézerfényforrás is the Hungarian term for a laser light source. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "LASER" is an acronym for Light Amplification by Stimulated Emission of Radiation. A laser light source produces a beam of coherent light, meaning the light waves are in phase with each other. This coherence distinguishes laser light from ordinary light sources, such as incandescent bulbs, which emit incoherent light.

Laser light sources are characterized by several properties. They emit monochromatic light, meaning the light is of a single wavelength or a very narrow band of wavelengths. The beam is also highly directional and collimated, meaning it spreads very little over distance. The intensity of laser light can be very high. Different types of laser light sources exist, utilizing various gain media such as gases, solids, liquids, and semiconductors, to produce light at different wavelengths and powers. These light sources find applications in numerous fields, including telecommunications, medicine, industry, research, and entertainment due to their unique properties.
