Laser Scattering
Laser scattering is a diagnostic technique used to study plasma by directing a laser beam into it. When the laser light interacts with the charged particles in the plasma, some of the light is scattered in different directions. By analyzing the scattered light’s properties—such as its intensity and frequency shift—scientists can gain insights into the plasma's characteristics, including density, temperature, and motion of the particles. This non-invasive method allows for real-time observation and understanding of plasma behavior, which is crucial in fields like fusion energy research and astrophysics.

Laser scattering is a phenomenon where a laser beam interacts with particles in its path, causing the light to change direction. When the laser light hits tiny particles, it can scatter in various directions. This scattering can reveal information about the particles, such as their size and composition. Scientists use this technique in various fields, from environmental monitoring to medical diagnostics, to analyze substances or detect pollutants. Essentially, laser scattering helps us "see" and understand materials by observing how light behaves when it encounters them.
