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 cutting bridge Laser cutting bridge A laser cutting bridge system in the world of textiles is an industrial machine for cutting and engraving of textile materials (i.e. fabrics). It is formed by a galvanometric laser head and laser source that runs along an horizontal beam (the bridge) supported by two lateral columns and sometimes by central columns. This system is placed over one or more embroidery machines, more frequently multi-head rather than single-head machines, cutting tables, roller devices, to cut out and/or engrave embroidered fabrics. The first laser bridge for embroidery machines was invented and realized in 1998 by GMI srl an
