摘要： A method for providing a hole through a metal engine component having a base metal and thermal barrier coating layer forming a top surface of the component, the hole having a central axis extending at a hole angle of 20 degrees or less with respect to the top surface. The method includes laser trepanning through the thermal barrier coating layer without penetrating the base metal by moving a central axis of a pulse laser beam within a boundary of the hole, with the pulse laser beam having a first pulse energy level. The central axis of the pulse laser beam is then disposed within the boundary at the hole angle and shots of the pulse laser beam are applied to drill through the base metal and complete the hole, using a second pulse energy level different from the first pulse energy level.

摘要： A laser machine comprises: a head including optical parts allowing reflection of a laser beam or allowing the laser beam to pass through, while being rotatable about rotary axes, and a focusing optical system that focuses the laser beam; a moving mechanism that allows the head and a target to move relative to each other; and a control unit that controls rotations of the optical parts in such a manner that an irradiation intended position to be reached by an emission optical axis when the laser beam is emitted to the target moves in a curvilinear pattern or a linear pattern, controls movement by the moving mechanism so as to move the head and the target relative to each other, and controls emission output from the laser source so as to change a condition for emitting the laser beam based on the rotation angles of the optical parts.

摘要： A laser is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. A feature of utilizing a laser to create the openings for tissue integration builds from its tunability. More particularly, the laser precisely places openings in any pattern and location, and on any textile that forms the graft material. Further, the power and focus of the laser is precisely adjusted to control the diameter and shape of the openings. All parameters of the openings can be controlled at will, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel.

摘要： The techniques of this disclosure generally relate to a variable permeability layered prosthesis including an impermeable outer layer and a permeable inner layer. The impermeable outer layer is well suited to seal a dissection opening of a dissection. The permeable inner layer allows fluid to enter into a dead space between the impermeable outer layer and the permeable inner layer. The fluid in the dead space coagulates in the dead space providing a media for tissue growth into the prosthesis. The ability of tissue to integrate into the prosthesis provides biological fixation of the prosthesis in vessels and prevents endoleaks and migration of the prosthesis.

摘要： A laser machining apparatus includes a laser nozzle for supplying an assistive gas to remove undesirable materials and applying a laser beam at an angle, which is inclined with respect to a surface of a workpiece, a sputter blocking jig disposed over a region of the workpiece that is irradiated with the laser beam, so as to lie across directions in which the laser beam is scattered, and for blocking sputtered particles that are generated from the surface by the applied laser beam, and a joint connecting the laser nozzle and the sputter blocking jig to each other. The joint moves the laser nozzle and the sputter blocking jig in synchronism with each other.
