Laser-Induced Fluorescence

Laser-Induced Fluorescence (LIF) is a diagnostic technique used to study plasmas, which are ionized gases found in environments like stars or fusion reactors. In LIF, a laser beam excites specific particles, causing them to emit light as they return to their original state. By analyzing this emitted light, researchers can gather detailed information about the particles' energy levels, density, and temperature. This helps scientists understand plasma behavior and improve technologies like fusion energy or semiconductor manufacturing, offering insights into fundamental processes in both astrophysics and engineering applications.
