Laser laser devices. The question of just how to assign credit for inventing the laser remains unresolved by historians. On May 16, 1960, Theodore H. Maiman operated the first functioning laser at Hughes Research Laboratories, Malibu, California, ahead of several research teams, including those of Townes, at Columbia University, Arthur Schawlow, at Bell Labs, and Gould, at the TRG (Technical Research Group) company. Maiman's functional laser used a solid-state flashlamp-pumped synthetic ruby crystal to produce red laser light, at 694 nanometers wavelength; however, the device only was capable of pulsed operation, because of its three-level pumping design scheme. Later that year,
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
