The machines employ laser for the cutting action and any type of laser can be employed to perform the lasing action. Some of the types of lasers are High Precision Laser Cutting, Fiber Laser Cutting and 3D Laser Cutting .
Nd:YAG Laser is a solid state laser device. Here, YAG stands for Yttrium Aluminium Garnet. The triply ionized neodymium replaces a fraction of yttrium from the YAG crystal and starts emitting laser waves. They are most commonly used in medical field for the treatment of cataract and glaucoma. They are also used in treatment of cancer. They are also used in spectroscopy, laser pumping, military rangefinding, etc.
A fiber laser is one such laser in which an optical fiber is doped with rare earth elements like ytterbium, erbium, neodymium, holmium, etc. and these elements act as active gain medium. These are doped fiber amplifiers which do not need laser for providing light amplification. These lasers are used in material processing, engraving, cutting, etc.
3D Laser cutter employs automated laser torch to cut the workpiece from all the directions. It is used in automotive industry & furniture industry. 3D Laser work together with robotic system to enable.
The YAG cutting machines are small powered machines which require upto 600 W power. These machines are fast in cutting thin metals. The fiber laser cutting machine is a high power machine of the order of 300w – 8KW. They are very consistent and fast in cutting thick materials. The CO2 Laser cutting machine also requires high power of up to 2-6 KW and are used mainly for cutting thick materials. The 3D Laser cutting machine and fiber laser combines with the robotic automated hand to cut in different axes and orientation.
