The laser cutting process started in the mid-60s after plasma cutting had been in use. It's a precise thermal cutting process that uses a focused beam of amplified laser light during its operation process. Laser cutting is usually performed using a Computer Numerical Control (CNC), to enable perfect and extreme accuracy when cutting workpieces. The optics help the laser light focus on a small point and become smaller and hotter as the laser light enters the optics. Then, the computer controls the focused laser beam of light to cut through the workpiece.
The three primary types of lasers used in laser cutting: CO2 laser, neodymium (Nd) and Yttrium-Aluminium-Garnet (Nd: YAG)
