The method for the production of a laser beam for surface processing, comprises emitting the laser beam with a first beam parameter product from a laser beam source and then deforming into a laser beam with the predeterminable beam parameter product via an optical unit, where the beam ...
PURPOSE:To enable efficient manufacture of fine cut-out patterns by plading metallic pattern masks on sheet materials on a disc table, rotating the table, scanning a laser beam while sucking air by a vacuum pump from below and cutting out the materials. CONSTITUTION:Metallic pattern masks 10 ar...
support (1) being made of at least one extruded element (2), which is wound to form a plurality of windings (11, 12, 13) and the connection portions (7, 8) of which are connected to one another at least in portions by a connection seam (15), preferably formed as a laser weld ...
PURPOSE:To improve the quality of cut-out patterns and to increase the speed of production by brinding upper and lower stainless steel masks sandwiching thin materials into press contact with each other by electromagnets and cutting out the fine patterns to the material by a laser beam. CONSTITU...
A new method of Mo+ ion beam production is presented in the paper. The method bases on the chemical sputtering/etching of the molybdenum parts (e.g. anode) of the arc discharge ion source by the chloride containing plasma. A mixture of CCl4 (or CHCI3) vapor and air was used as the...
The invention relates to a beam bottom, comprising a concrete slab (1) with main reinforcement bars (2) for said beam extending in the longitudinal direction therein, and with stirrups (3) extending in the transverse direction of the concrete slab (1) and intended for absorbing transverse forc...
(2).(2)[Math Processing Error]where, fb is the absorption proportion of laser energy by copper wire, R0 is the radius of laser beam, and v is welding speed. During laser transmission welding, The temperature distribution is uneven. The non-linear thermo-physical properties of PMMA and ...
A laser ion source has been developed as a high-intensity source for the ion implanter and the single pulsed beam of the azimuthally varying field cyclotron at TIARA. Highly charged beams of Cand Cions and low-charged beams of heavy ions such as C, Al, Ti, Cu, Au, and Pt are ...
the fiber-melting technique does not provide adequate flexibility to fabricate a ball lens with optimal balance among working distance, resolution, and depth of focus (DOF)9,20. Additionally, the fabrication of a beam reflector in a fiber ball-lens-based OCT probe involves the use of an angle...
6b). The probe was motorized providing transversal movement of the laser beam patrolling on the surface of the nanofibrous film (Fig. S19a). The Raman spectra were preprocessed before model building for the fiber quantities. GA was used again for variable selection, the final PLS-GA model ...
