Laser cutting|One of the key technologies of manufacturing
Laser cutting is ideal for manufacturing and other industrial applications that require powerful cutting tools with high precision. As products become smaller, more functional, more complex, and smaller and smaller, laser cutting and laser processing are usually the only methods that can produce the high-precision features required by these devices. Achieving the best laser cutting results depends on matching the appropriate laser pulse width and wavelength to the material to be processed. The shorter the pulse width, the better the cutting effect, and the fewer burrs or defects (such as the heat-affected zone (HAZ)).

Ultrafast lasers defined as pulse widths equal to or less than 10 picoseconds (1 ps = 10 -12 sec) are becoming more and more popular in cutting. The high power laser pointer beam strips electrons from the atoms in the material, ionizes the atoms and forces them to explode from the bulk material, with little heat transfer. Femtosecond lasers are faster-the pulse width lasts only a few femtoseconds (1 fs = 10 -15 seconds), and they produce the least thermal damage. They are essential for the high-precision manufacturing of medical devices, especially those with microscopic features or Made of special materials.
