Plasma shielding

  "id": "MLC-T-CHM-009017",
  "term": "Plasma shielding",
  "field": "Chemistry",
  "definition": "The phenomenon where a dense plasma formed at a surface absorbs or reflects incident laser radiation, preventing it from reaching the target material. This effect reduces the efficiency of laser-material interaction, particularly in laser ablation or welding processes. It is more pronounced with higher laser power densities and longer pulse durations.",
