Tokamak question: What happens when you shine a laser on the plasma?

Click For Summary
SUMMARY

When a laser pointer is directed at plasma within a tokamak, the magnetic field does not affect the photons. Instead, the photons interact primarily with plasma ions, electrons, and other particles depending on the plasma's temperature. This interaction may not be visually observable like a laser beam through cloud vapor, as the photons are likely absorbed or scattered rather than passing through unimpeded. The discussion highlights the importance of understanding photon behavior in plasma diagnostics.

PREREQUISITES
  • Understanding of plasma physics
  • Familiarity with tokamak design and operation
  • Knowledge of laser interferometry techniques
  • Basic principles of photon interaction with matter
NEXT STEPS
  • Research "Laser interferometry in plasma diagnostics"
  • Study "Photon scattering mechanisms in plasma"
  • Explore "Tokamak plasma confinement methods"
  • Investigate "Effects of temperature on plasma ion behavior"
USEFUL FOR

Physicists, plasma researchers, and engineers involved in fusion technology and diagnostics will benefit from this discussion.

TL;DR
Pointing a laser into a tokamak whilst it's running
I really enjoy learning strange facts and while i would never assume to be a "Smart" person i do have the power to ask.

So with a plasma fusion reactor like the tokamak or any other they have a viewing window to see the plasma bound in the toroidal magnetic field so what would happen if you were to point a laser pointer through the window and fire excited photons into the plasma?
Would you see them passing through the plasma, would they just be destroyed, would they be instantly adhered or bounced back by the magnetic field?
Cheers guys and girls

Magnetic field has no effect. Photons most likely would interact with plasma ions.

so interacting with the plasma ions would it be visible like a laser through cloud vapor?

Thank you Astronuc, As high as most of that information went above my head it was a very interesting read and answered my question.
Thank you
