The laser is a device capable of emitting a beam of coherent light, monochromatic and concentrated in a rectilinear radius extremely bright, collimated through the process of stimulated emission.
These three properties are the basis of the wide range of applications that the laser devices have had, and continue to have in various fields: very high brightness, generated by concentrating a lot of power in a very small area, the laser gives the ability of cutting, engraving and welding metals.
The laser beam is a universal tool for cutting, welding and surface treatment. Works without contact, and then without any problem of wear. laser cutting works without leaving burrs at the corners, with a small slit cutting and high feed rates and with minimal delays in the production of the piece, as well as the quenching of the edges. These are just some examples which show the technological advantages and the productivity of processing the material resulting from the use of the laser. The development of laser systems in the industrial field in the eighties has brought a revolution in materials processing. The high power density at the focus of the laser beam to beam manages to blend almost any material in thousandths of a second, without contact and transport of energy. This enables high speed processing and a minimum heat input to the workpiece with a reduction in wear. The laser beam cuts thick steel sheets, steel reactors evaporates and divides the hardest materials in nature, from diamonds to textile materials, from glass to wood laminates.
The laser beam is shown as a multipurpose tool: processing occurs without contact with a reduced thermal influence; any profile in thin or thick material can be cut with precision and very high speed and with outstanding quality cutting edges.
