Laser science awarded the Nobel Prize in Physics in 2018 for groundbreaking inventions in the field of laser physics. The first working laser (a pulsed ruby laser) was demonstrated on May 16, 1960, by Theodore Maiman at the Hughes Research Laboratories. Laser science Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of the light field in the laser. It is also concerned with the physics
Constructed language for said conlang to be used as an auxiliary language. There are no rules, either inherent in the process of language construction or externally imposed, that would limit a constructed language to fitting only one of the above categories. A constructed language can have native speakers if young children learn it from parents who speak it fluently. According to "Ethnologue", there are "200–2000 who speak Esperanto as a first language". A member of the Klingon Language Institute, d'Armond Speers, attempted to raise his son as a native (bilingual with English) Klingon speaker. As soon as a constructed language has a
