NdYAG lasers operate on the principle of stimulated emission, where a ruby laser rod doped with neodymium and yttrium is excited by an electrical pulse. This excitation causes electrons to drop from a higher energy state to a lower one, emitting light in the process. The emitted light is channeled through an output aperture, creating a focused beam. This beam is versatile and can be adjusted to handle a wide range of materials, from thin sheets to thick metals.
In metalworking, NdYAG lasers are essential for precise cutting, welding, and marking operations. Their ability to produce highly accurate cuts and intricate engravings is crucial for applications in industries such as automotive and aerospace. For example, in automotive manufacturing, NdYAG lasers are used for fabricating complex engine components and personalizing luxury vehicles.
