The technical study of laser cutting for cardiovascular stents was fulfilled. It is a typical application of laser micro-fabrication. The discipline of influence of the technological parameters (including the focal length of lens, focus position, laser power, cutting speed, pulse frequency, pulse width and assist gas pressure) on the quality of the cardiovascular stents were obtained with the most advanced fiber laser in the world. The results show that the kerf width increases with the increase of laser power, pulse frequency, pulse width and assist gas pressure, but decreases with the increase of cutting speed. The optimal technological parameters for cutting cardiovascular stents with laser were acquired on the base of the experiment. Stents whose kerf width is less than 20 μm were cut after a lot of experiments.
