Automated Optimization Techniques Improve Illumination
Dec 1, 2005 — A group at the Institute of Solid State Physics at Technische Universität Berlin in Germany is using a metallorganic chemical vapor deposition reactor for the fabrication of a variety of semiconductor heterostructures. The wafers under fabrication are heated with an infrared lamp, which could not change temperature fast enough for a particular application and could not reach sufficiently high temperatures. The reactor, an AIX 200/4 from Aixtron AG of Aachen, Germany, consists of a big glass...
Nd:LuVO4 Laser Pumped
Mar 1, 2004 — The vanadate crystals YVO4 and GdVO4 have been very successful hosts for diode-pumped rare-earth-ion lasers because their stimulated-emission and absorption cross sections are significantly higher than other hosts, such as YAG. Now a collaboration...
Researchers Around the World Obtain Vanadate Improvements
Jan 1, 2004 — Neodymium-doped vanadate has become the crystal of choice for many diode-pumped lasers, primarily because the absorption cross section for 808-nm laser-diode pumping to the neodymium upper laser level is nearly eight times greater than the...
