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
Laser (dinghy) for this rig is 110–145 lb (50–65 kg), thus becoming an ideal boat for young sailors moving from the Optimist/RS Tera who are still too light for a normal Laser. The Laser 4.7 rig has a UK Portsmouth Yardstick number of 1200. The "Laser M Rig" is no longer in production. It was the first attempt at making a smaller rig for smaller sailors. It employed the same lower mast section, but a shorter top section. This variant differed when compared to the other unmodified rigs. This is primarily because the shorter top section didn't allow enough bend to be
