Single mode fiber lasers are sensitive to penetration spiking power modulation and beam rotation can minimize this effect
Comparative analysis of GMA, laser, and laser-GMA hybrid welding
Comparative analysis of GMA, laser, and laser-GMA hybrid welding shows that laser and laser hybrid welding are very attractive for high and ultra high strength steels
Electrical-Mechanical-Systems
By: Norbert Lorenz Over the past few years the interest in Micro-Electro-Mechanical-Systems (MEMS) and Micro-Optical-Electrical-Mechanical-Systems (MOEMS) from research institutions, industrial firms and the press has risen considerably. Of particular interest are lab-on-a chip devices where many subsystems (ICs and MEMS) are assembled to a functional system for medical and bio-photonic applications. To date the main […]
Carbon Nanotubes (CNTs)
By: Masoud Mahjouri-Samani Limitations of current technology and demands for smaller, faster, more efficient and cost effective electronic and optical devices have provoked scientists and researchers around the world to find new materials which satisfy their needs. The extraordinary characteristics and properties of carbon nanotubes (CNTs) have made them promising candidates for fabricating nano-scale electronics […]
Effect of grain size on laser machining of alumina
Laser machined lines on alumina shorter sintering time, smaller grain size, finer lines
