• Magnetic pulse welding — (MPW) is a welding process that uses magnetic forces to drive two workpieces together and weld them together. The welding mechanism is most similar to that in explosion welding.[1] Process A very high AC current (the primary current ) is passed… …   Wikipedia

• Terahertz time-domain spectroscopy — In physics, terahertz time domain spectroscopy (THz TDS) is a spectroscopic technique where a special generation and detection scheme is used to probe material properties with short pulses of terahertz radiation. The generation and detection… …   Wikipedia

• Q-switching — Q switching, sometimes known as giant pulse formation, is a technique by which a laser can be made to produce a pulsed output beam. The technique allows the production of light pulses with extremely high (gigawatt) peak power, much higher than… …   Wikipedia

• ISKRA lasers — The ISKRA 4 and ISKRA 5 lasers are lasers which were built by the Russian Federation at RFNC VNIIEF in Arzamas 16 ( ru. Арзамас 16) with the approximately 2 kJ output ISKRA 4 laser being completed in 1979 and the 30 kJ output ISKRA 5 laser which… …   Wikipedia

• Fiber laser — A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers,… …   Wikipedia

• Quantum well — A quantum well is a potential well with only discrete energy values. One technology to create quantization is to confine particles, which were originally free to move in three dimensions, to two dimensions, forcing them to occupy a planar region …   Wikipedia

• Neodymium-doped yttrium lithium fluoride — (Nd:YLF) is a lasing medium for arclamp pumped and diode pumped solid state lasers. The YLF crystal (LiYF4) is naturally birefringent, and commonly used laser transitions occur at 1047 nm and 1053 nm. It is used in Q switched systems in part due… …   Wikipedia
