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
Polariton laser Review Letters" in May 2013). The investigations performed by the team in Würzburg, having started with the idea of engineering an electrical device in 2007, led to the desired effect after a few years in cooperation with their international partners from the U.S., Japan, Russia, Singapore, Iceland and Germany. Finally, their studies were complemented by a crucial experiment in a magnetic field: an unambiguous verification of the emission-mode's matter component in the polaritonic laser regime was given, yielding a first-time experimental demonstration of an electrically pumped polariton laser by C. Schneider, A. Rahimi-Iman and co-authors in the team of S.
