Excimer

clipping noun
Excited dimmer in lasers. “A short-lived dimeric or heterodimeric molecule formed from two species, at least one of which is in an excited state. Often diatomic and formed between two molecules or atoms that wouldn't bond if they were in the ground state.” (Wikipedia)
 
"Our high-power excimer laser mirrors are multi-layer dielectric coated mirrors designed for use with high energy excimer lasers."
Etymology : Blend between 'excited' "magnetically or electrically stimulated" from O.Fr. esciter (12c.) or directly from L. excitare "rouse, call out, summon forth, produce" and 'dimmer' from O.E. dimm "dark, gloomy, obscure," from P.Gmc. *dimbaz. (Etymonline)
