What is laser amplification?

Answer 1

Laser amplification is the process of increasing the intensity of light through stimulated emission of radiation. In this process, photons stimulate excited atoms or molecules in a gain medium, causing them to emit additional photons that are coherent and in phase with the initial light. This amplification occurs within a laser cavity, where the light is reflected back and forth to build up its intensity before being emitted as a focused beam. The result is a highly concentrated and coherent light output characteristic of lasers.
