Laser[1][2][3] (-eris, n., nom. pl. -era;[1][4] aliquando -er, -eri, m.,[3] vel indecl., n.), vel instrumentum lasericum,[5] est apparatus qui lucemcohaerentem(d) (radium lasericum[6]) per emissionem stimulatam radiationis electromagneticae generat. Vocabulum Anglicum laser est acronymum pro light amplification by stimulated emission of radiation.[7] Lasera ab aliis luminibus eo differunt, quod lucem cohaerentem emittunt.
Cf. Leo Latinus(25 Decembris2014)."Epistula LXXXIII".Epistulae Leoninae: 19: “… quia laseribus (*laser, -eris, n. – Laser = Light Amplification by Stimulated Emission of Radiation) caeruleis in discum compactum multo plura data imponi possunt quam rubris.”
