Lasers in industry
In industrial applications, two basic laser types are used for materials
processing - the CO2 laser and the Nd:YAG laser. The two laser
types generate
light in the infrared range of the spectrum, which means that the laser beam
itself is not visible. The operator must take adequate safety precautions using
safety goggles and spectators and other workers must be protected by machine
enclosures.
After the laser beam exits the resonator it is directed through the beam path to
the cutting or welding head, where it is focused onto the material surface.
The beam path can be a series of reflective copper mirrors (in case of CO2 laser
systems) or a optical fiber (in case of Nd:YAG laser systems).
Laser processing equipment is built in various ways: while some equipment manufacturers offer flying optics, others prefer to move the table under a stationary processing head. In laser cutting factors like drive technology, material gauge and the size of the working envelope will favor one or the other design; in laser welding the choice will be influenced more by factors like the clamping system, the weld edge preparation or the material handling concept.
