摘要:
A method of forming an internally-arranged laser-beam weld from within a composite structure. The method includes arranging a welding apparatus within an internal passage of the composite structure, and emitting a laser beam from the welding apparatus to form the internally-arranged laser-beam weld between layers of the composite structure.

The present application relates to a cutting head (1) for a device for cutting hair. The cutting head has an optical system (3) which directs a laser beam (7) across a cutting zone (8) in the cutting head. The laser beam has a fast and a slow axis. The optical system has a focus lens (6) configured to form a first focal point (11) of the laser beam in the cutting zone. In one embodiment, the optical system (3) also has a focusing element (15) which refocuses the laser beam to form a second focal point (16) of the laser beam in the cutting zone. In another embodiment, the focus lens forms a focal length of the laser beam in the cutting zone along its fast axis which is greater than a focal length of the laser beam in the cutting zone along its slow axis.

A method and system are disclosed for improving the appearance of skin utilizing an energy source, preferably a laser and more preferably an erbium laser device. The method includes using an energy source with or without pixilation adapted to be controlled by software or other means to achieve primarily coagulation to a limited depth of skin. Using this process, no appreciable ablation occurs and the superficial epidermal layer is not completely removed, thereby minimizing post-operative recovery time, patient pain, and post-operative risks.

The surgical instrument comprises a handpiece (1), associated with which is a tip (5) forming a wave guide and terminating with an operating end, intended to act on the tissues and from which a laser radiation is emitted and which receives said laser radiation from fiber optic means (4). The tip is implemented to collect the laser emission coming from a plurality of optical fibers couplable with said tip at a coupling face and to convey said laser emissions towards said operating end.
摘要:
A hand-held laser welding wand (100) includes a reflection shield (150) that reflects laser light that is reflected off a work piece surface away from the hand of a user of the hand-held laser welding wand (100). The shield (150) also reflects the thermal radiation. transmitted from the work piece toward the wand during the weld process. This will help guard against a user of the wand (100) absorbing laser light that may be reflected off the work piece, as well as significantly reduce any heat that might be transferred to the wand (100) as a result of the reflected laser light.
摘要:
A method, apparatus and system for template-controlled, precision laser interventions is described for microsurgery, and industrial micromachining. The system includes a user interface, wherein the user can either draw, adjust, or designate particular template patterns overlaid on live video images of the target and provides the means for converting the template pattern into a sequence of laser shots on the corresponding surgical or industrial site. The user interface also continuously presents three dimensional visual information to the surgeon/user during the operation. The system thus comprises the following key elements: (a) a user interface (19), consisting of a video display (18), microprocessor (16) and controls, (b) an imaging system (86), including a surgical video microscope with zoom capability, (c) an automated 3D target acquisition and tracking system (84, 85, 82) that can follow the movements of the tissue, during the operation, (d) a laser, (e) a diagnostic system, incorporating a mapping and topography means (98) for measuring precise surface shapes prior to and subsequent to a procedure.
摘要:
A laser-based method and apparatus for corneal surgery. The present invention is intended to be applied primarily to ablate organic materials, and human cornea in particular. The invention uses a laser source which has the characteristics of providing a shallow ablation depth (0.2 microns or less per laser pulse), and a low ablation energy density threshold (less than or equal to about 10 mJ/cm ), to achieve optically smooth ablated corneal surfaces. The preferred laser includes a laser (102) emitting approximately 100-50,000 laser pulses per second, with a wavelength of about 198-300 nm and a pulse duration of about 1-5,000 picoseconds. Each laser pulse is directed by a highly controllable laser scanning system (104).
