In medical device manufacturing, ultrafast laser technology is widely used in precision cutting, welding, marking, and surface treatment. For example, in the manufacturing of cardiovascular stents, ultrafast laser cutting technology can achieve precise cutting of small-sized stents, with diameters up to 400 microns or less and wall thicknesses of tens of microns, while traditional laser cutting is limited by thermal effects and typically has a diameter of no more than 2 millimeters. In addition, ultrafast lasers can also process biodegradable materials such as magnesium alloys and polylactic acid, avoiding the risks of melting and combustion. The cutting surface is smooth and free of burrs, meeting the requirements of biodegradable scaffolds.
