Laser miliatary aviation, due to the potential to temporarily distract or blind pilots. See Lasers and aviation safety for more on this topic. Laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light
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
