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 guided and stabalized arc welding Laser guided and stabalized arc welding Laser guided and stabilized welding (LGS-welding) is a process in which a laser beam irradiates an electrical heated plasma arc to set a path of increased conductivity. Therefore, the arc´s energy can be spatial directed and the plasma burns more stable. The process must be destincted from laser-hybrid welding, since only low power laser energy of a couple hundred watts is used and the laser does not contribute significantly to the welding process in terms of energy input. The principle of Laser enhanced welding is based on the interaction between the electrical arc and
