INDUSTRIAL APPLICATIONS OF LASER
There are literally thousands of references on the theory and practical uses of lasers. They are used in everything from portable CD players to sophisticated weapons systems. The term LASER is an acronym for "Light Amplification by Stimulated Emission of Radiation," and is defined as "any of several devices that emit highly amplified and coherent radiation of one or more discrete frequencies." At Northeast Laser &Electropolish, we utilize pulsed Nd:Yag (Neodymium-Doped Yttrium-Aluminum- Garnet) type lasers for welding. The Nd:Yag rod, when stimulated by a flash lamp, emits light in the ultraviolet range with a wavelength of 1.06 microns. This light is then focused and delivered to the workpiece, where the high energy density beam is used to weld.
