Excimer laser

  "id": "MLC-T-CHM-004176",
  "term": "Excimer laser",
  "field": "Chemistry",
  "definition": "A type of gas laser that generates coherent ultraviolet light by stimulating the emission from an excimer, which is a short-lived diatomic molecule formed from two atoms when at least one is in an electronically excited state. These lasers typically employ noble gas halides, such as ArF, KrF, or XeCl, as the active medium. Excimer lasers find applications in photolithography, micromachining, and ophthalmology due to their high photon energy and short pulse duration.",
