Welding with High Power Diode Lasers
Laser welding with CO2, fiber and various types of solidstate lasers is a well established process currently utilized in a wide range of industries and applications. However, recent technological developments in high power diode laser technology have expanded the capabilities of laser welding, as well as changed its cost characteristics. As a result, diode lasers are poised to replace tradition...
متن کاملPushing Power Density Limits using SiC-JFet-based Matrix Converter
The omnipresent trend of increasing the power density of inverter technology lead to new developments in semiconductor material. As most of the benefits come from higher operating junction temperatures, it is mandatory to restrict the inverter design to peripheral components capable to work in these high temperature conditions. Eliminating the needs for large DC-link capacitors, the matrix conv...
متن کاملPushing the limits of crystallography
A very serious concern of scientists dealing with crystal structure refinement, including theoretical research, pertains to the characteristic bias in calculated versus measured diffraction intensities, observed particularly in the weak reflection regime. This bias is here attributed to corrective factors for phonons and, even more distinctly, phasons, and credible proof supporting this assumpt...
متن کاملPushing the limits of SPM
Breaking the speed limit One of the serious, inherent limitations in all forms of SPM is the low imaging rate. This is because each image is built up pixel by pixel in a sequential scan of the surface. The scanning motion involves electronically controlled mechanical displacements, and usually some form of feedback is applied between a control parameter, such as tunneling current or force, and ...
متن کاملHigh-Power Continuous-Wave Directly-Diode-Pumped Fiber Raman Lasers
We describe novel fiber Raman lasers pumped directly by spectrally combined high power multimode laser diodes at ∼975 nm and emitting at ∼1019 nm. With a commercial multimode graded-index fiber, we reached 20 W of laser output power with a record slope efficiency of 80%. With an in-house double-clad fiber, the beam quality improved to M = 1.9, albeit with lower output power and slope efficiency...
