  "id": "MLC-T-CHM-009759",
  "term": "Quantum cascade laser",
  "field": "Chemistry",
  "definition": "A semiconductor laser that emits electromagnetic radiation in the mid- to far-infrared region of the spectrum. It operates by exploiting electronic transitions between quantized energy levels within a superlattice structure. These lasers are widely used in applications such as gas sensing, spectroscopy, and medical diagnostics due to their compact size and tunable output.",
