The invention belongs to the technical field of laser machining, and particularly relates to a Bessel laser beam rotary-cut punching device based on a Dove prism. An ultrafast laser rotary-cut punching device comprises an ultrafast laser, a laser beam energy distribution conversion system, a laser incidence direction adjusting system, a laser polarization state balance system, a rotary optical system, a balance optical system and a Bessel laser beam dynamic focusing system, wherein the laser incidence direction adjusting system is composed of three wedge-shaped prisms, so that the machining precision is greatly improved while the low machining cost is kept; the laser beam energy distribution conversion system and the Bessel laser beam dynamic focusing system are combined to form a Bessel beam realization system suitable for the Dove prism; and in addition, the Bessel beam is used for conducting laser rotary-cut micropore machining, so that compared with an existing micropore machining mode, the precision of a machined micropore is effectively improved, the taper controllability of the micropore is improved, and the depth-diameter ratio of the machined micropore is increased.
Description
technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a rotary cutting and drilling device based on a Bessel ultrafast laser beam of a Dove prism. Background technique [0002] With the development of manufacturing technology and microfluidic technology, micropores or micropore arrays with diameters of tens or hundreds of microns are widely used in many fields such as aerospace, energy, automobile manufacturing, etc., and with the improvement of related performance requirements, its The size, precision, shape and aspect ratio of micropore manufacturing put forward higher-level requirements. Traditional machining methods such as machining, electrical discharge machining, and electrochemical machining are no longer suitable for today's requirements for micro-hole manufacturing due to the limitations of machining size, material selectivity, and precision. Compared with traditional machining methods, laser machining...
