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
Sazhen-S Sazhen-S Sazhen-S () is a Soviet laser/optical space surveillance system, used to analyse the orbital parameters of space craft. There are several installations across the former Soviet Union. One of which is based at space ground station NIP-19 near Dunaivtsi in Ukraine. It is named after the sazhen, a former Russian unit of measurement which translates as fathom and has a length of . A similar system is Sazhen-T. A number of Sazhen-S installations were constructed at the network of scientific monitoring stations. At least two are now in Ukraine - one in Dunaivtsi and another at Yevpatoria. At least
