Which classification of lasers is primarily used for industrial cutting applications?

The classification of lasers that is primarily used for industrial cutting applications is Class 4 lasers. This category encompasses high-powered lasers that exceed the safety limits of lower classifications, meaning they can produce significant thermal effects and are capable of cutting through various materials, including metals and plastics.

Class 4 lasers are essential in industrial settings because they provide the necessary power and precision for cutting tasks. They can focus a great deal of energy on a small area, effectively melting or vaporizing the material. In addition to cutting, Class 4 lasers are used for other applications, such as welding, engraving, and other processes that demand high energy output.

In contrast, Class 1 lasers are low-power devices typically safe for use under all conditions, Class 2 lasers are visible light lasers that can cause eye damage if viewed directly for extended periods, and Class 3 lasers have restricted applications due to their potential to cause harm but are not suited for heavy industrial cutting tasks. Thus, Class 4 lasers are clearly the most appropriate choice for intensive industrial applications involving cutting due to their power and capacity for material processing.
