Technology

Laser cutting is a technology that uses a laser to cut metals and non-metals, such as wood,
plastics, acrylics, paper, and glass, and it is typically used for industrial manufacturing
applications. Laser cutting works by directing a high-power laser beam at the material, which
then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with
a high-quality surface finish. CO2 lasers are mainly used for cutting metals.

9.3–10.6 ㎛ wavelength of CO2 lasers are used for cutting non-metals including paper, wood,
plastics, and glass. This is because the wavelength of the CO2 lasers is absorbed well by these
materials. Advantages of laser cutting over mechanical cutting include easier handling and
reduced contamination of workpieces. There is also a reduced chance of warping the material
that is being cut, as laser systems have a small heat-affected zone. Plasma cutting machines are
mainly used to cut thick materials and materials that absorb less laser beam including aluminum
and bronze. Newer laser machines operating with higher power and enhanced beam quality
are approaching plasma machines in their ability to cut through thick materials.
