  "id": "MLC-T-CHM-013372",
  "term": "Parametric amplification",
  "field": "Chemistry",
  "definition": "A process in which a signal is amplified by varying a parameter of the system at twice the signal frequency. In optics, this involves using a nonlinear optical medium to amplify a weak signal beam by transferring energy from a strong pump beam. This technique is used in optical parametric oscillators and amplifiers.",
