  "id": "MLC-T-CHM-006086",
  "term": "Ion laser",
  "field": "Chemistry",
  "definition": "A type of continuous-wave gas laser in which the gain medium is a plasma of noble gas ions, such as argon or krypton. An electrical discharge excites the gas, creating a population of positive ions that serve as the lasing species. These lasers produce multiple emission lines in the visible and ultraviolet regions of the spectrum, with common argon-ion wavelengths being 488.0 nm and 514.5 nm.",
