The Simulation of Laser Beam Welding of Silica Elements
The laser beam welding of silica represents an innovative alternative to traditional oxyacetylene welding. The application of this technology allows an economic bonding of silica components, which raises the standards of joint qualities to a new level. In a research project, the Bauhaus-Universität Weimar analyzes the CO2-laser beam welding of silica elements numerically and experimentally in c...
متن کاملDiffractive beam splitter for laser Doppler velocimetry.
A miniaturized sensor head for the optical measurement of velocities of fluids based on laser Doppler velocimetry is demonstrated. Holographic optical elements mounted on a glass substrate are used for beam splitting and deflection. Volume holograms in dichromated gelatin exhibit good optical efficiency (75% transmission of a cascade of two holographic optical elements). With diffractive device...
متن کاملImproving Laser Beam Welding Efficiency
Laser beam welding is becoming widely used in many industrial applications. This paper reviews recent research conducted on the performance, potential and problems of thick section butt joint laser welding. Common defects that occur in laser beam welding with high power laser welding are discussed and possible solutions proposed. Methods of welding process efficiency improvement are analyzed.
متن کاملBeam-shaping optics delivers high-power beams
The development of laser diodes that deliver more than 10 W of output has changed the picture of the laser market. High-power devices now offer many advantages over conventional lasers of similar power levels, such as carbon dioxide or lamp-pumped Nd:YAG lasers. Their high efficiency (>30% wall-plug efficiency) promotes compact size as well as simplicity in power supply and cooling, which make ...
متن کاملTransverse Ion Beam Shaping Using Nonlinear Optics
Taking an advantage of the unique capabilities of heavy ion beams and continuously increasing beam intensity, many successful experiments on high energy density (HED) matter have been carried out at GSI over the past few years. New fascinating experimental proposals such as investigation of equation-of-state of matter under extreme conditions [1] and generation of metallic hydrogen utilizing io...
