(under subclass 301.16) Compositions in which the luminescent material either (1) can be stimulated to emit coherent light or other electromagnetic radiation, i.e., optical maser, or (2) luminesces under exposure to ionizing radiation, i.e., radio-photoluminescent.

117, Single-Crystal, Oriented-Crystal, and Epitaxy Growth Processes; Non-Coating Apparatus Therefor, for processes and non-coating apparatus for growing therein-defined single-crystal of all types of materials, including those which may be suitable as or to produce a lasing or scintillating composition. Class 118 generally provides for coating apparatus, including single-crystal (e.g., epitaxy) coating means.
372, Coherent Light Generators, appropriate subclasses for lasers.
