Combustion Diagnostics: Rayleigh and Raman Scattering
Rayleigh and Raman scattering techniques use laser light to probe combustion processes. The scattered signal provides information about the molecular composition, temperature, and flow properties, enabling detailed analysis of combustion dynamics.
Thomson scattering for plasma diagnostics
Plasma is a state of matter characterized by the presence of a significant portion of charged particles in any combination of ions or electrons. It is mainly characterized by the density, temperature, and distribution in space of each charged particle composing the plasma.
Plasma Diagnostics: Thomson Scattering
Thomson scattering consists in illuminating a plasma with a laser, and analyze the scattered light in order to retrieve the temperature and density of electrons.
Structure Diagnostics: X-ray Diffraction and Absorption
When matter is placed in extreme conditions (e.g., high pressure or temperature), X-ray sources are used to analyze its properties:
- X-ray diffraction (XRD): reveals the structural evolution of the material.
- X-ray absorption spectroscopy: provides information on the local atomic environment. Techniques include:
- XANES (X-ray Absorption Near Edge Structure) for electronic and chemical state information.
- XAFS (X-ray Absorption Fine Structure) for detailed atomic-scale structural information.
Amplitude’s high-energy ultrafast lasers, from Ti:Sapphire systems to Ytterbium platforms, provide the required stability, pulse shaping, and precision to drive advanced diagnostics in combustion science, plasma physics, and extreme matter studies.
