Abstract:
For a long period of time, lasers are being used more extensively in the field of materials processing, becoming the preferred choice for many industrial applications. Lasers together with laser materials processing machines, perform these operations with very good precision and high speeds. High power disk lasers offer high output power and excellent beam quality at appreciable efficiencies. In the case of solid metallic materials processing, continuous wave lasers or pulsed wave lasers are used, depending on the material’s properties and the type of application such as cutting, welding and cladding or ablation and drilling respectively. Materials with high reflection coefficient can, also, be processed with this technology.
