摘要： A system for pulsed synchronized laser cutting of stents and/or other medical products includes a numerical controller and a machine for moving a tube of material during cutting. A pulsed fiber laser is configured to cut the tube into, for example, a stent, the numerical controller being in communication with the machine and configured to send movement control information to the machine. The numerical controller may also receive movement speed information from the machine. The numerical controller is also in communication with the pulsed fiber laser and is configured to send pulse control information to the pulsed fiber laser. The numerical controller is configured to cause average laser power to decrease by decreasing frequency of laser pulses as stent cutting speed decreases, and to cause average laser power to increase by increasing frequency of laser pulses as stent cutting speed increases.
摘要翻译：用于支架和/或其他医疗产品的脉冲同步激光切割的系统包括数字控制器和用于在切割期间移动材料管的机器。脉冲光纤激光器被配置为将管切割成例如支架，数字控制器与机器通信并被配置为向机器发送运动控制信息。数值控制器还可以从机器接收移动速度信息。数字控制器还与脉冲光纤激光器通信，并配置为向脉冲光纤激光器发送脉冲控制信息。数值控制器被配置为通过降低激光脉冲的频率来降低平均激光功率，因为支架切割速度降低，并且由于支架切割速度增加，激光脉冲的频率增加导致平均激光功率增加。
