At XSOF™, we create custom fiber optic solutions for a wide variety of different laser applications, including cutting, welding, engraving and much more. Lasers are widely used in manufacturing to perform several operations, such as:
- Surface treatment
- Pulsed laser deposition
In most laser applications, high optical intensities are applied to a small spot, which leads to intense heating, and where it is required, evaporation and plasma generation.
Laser processing methods have many advantages when compared to mechanical approaches. They allow the fabrication of very fine structures of high quality, avoiding mechanical stress such as caused by mechanical drills and blades. A laser with high beam quality can be used to drill very fine and deep holes for applications such as injection nozzles. Lasers have higher processing speeds as well, and eliminate the lifetime limits of mechanical tools. Stresses that are normally introduced during mechanical processing are greatly reduced too, since raw materials can be processed without physical contact between the tool and the surface.
Lasers have many applications in material processing. Systems in the 50-300W range are used primarily for pumping of fiber lasers, plastic welding, and soldering applications. Lasers above 300W are used in brazing, thin metal welding, and sheet metal cutting applications.
The required brightness of the laser is higher for cutting applications than for brazing and thin metal welding. For example industrial materials that require more power, there are also lasers with average optical powers above 1 kilowatt. High power applications, such as hardening, cladding, and deep-penetrating welding, require multiple kW of optical power, and are used in a broad range of industrial processes.
