In this case, the material processing system comprises a laser source for irradiating the material and a spectrometer for capturing radiation data of the material.
  • The laser pulse creates a plasma plume, and the resulting thermal waves and mechanical shock waves lift all smaller particles in the material and produce a particle cloud.
