Description
?
Technical field
The invention belongs to the laser micro-machining technology field, relate to a kind of femtosecond laser device, particularly a kind of femtosecond laser device of Laser Processing intravascular stent.
Background technology
Present most of intravascular stent all adopts the mode of laser cutting to process, the main continuous or pulse laser of infrared band that adopts of traditional laser support cutting is as light source, move at support tubing upper edge line of cut by overlapped laser pulse or continuity point, import the auxiliary fusing cutting of hyperbaric oxygen simultaneously.
Material changes traditional laser because fuel factor makes all around, thereby influences machining accuracy.Simultaneously, laser focal spot material fusion and gasification, slag is blown out by gas, this processing method is seriously polluted, and motlten metal very easily splash has influenced crudy greatly to processing the support tube surfaces, support tubing is the tubing of small caliber, do not note to cause overheated in the process slightly and ablation, need to increase the high pressure assist gas and cool off, increased production cost.
The more important thing is that this form processing is favourable to processing metal tubing, but powerless for the degradable non-metal frame tubing of processing.
In sum, traditional Laser Processing form exist to be polluted environment, and crudy is poor, and precision is low to be caused overheated easily and ablate, can only processing metal tubing can't machining of non-metallic support tubing.In view of this, nowadays press for a kind of crudy height, processing unit (plant) that precision is high.
Summary of the invention
Purpose of the present invention is intended to solve at least one of above-mentioned technological deficiency, particularly solves the existing problem that the process equipment crudy is poor, precision is low.
