Guangdong found two rare giant reserves of over 3.6 million tons of rubidium mineral

Recently, the reporter from the Guangdong Provincial Department held prospecting projections are informed on the strategic action research briefing, after nearly three years of efforts, the province have been in Zijin County, Jiaoling County Wuyi mineralization belt of Guangdong Southern Section rare discovery mineral giant rubidium, rubidium two mineral resource estimate amounted to 3.6 million tons or more.

Rubidium manufacturing photomultiplier photocell, an important raw material radar, laser spectrometry as well as glass, ceramics, electronic clock and the like; in space technology, ion thrusters and thermionic energy converter requires a large amount of rubidium; hydride Rubidium and borides can be used for high-energy solid fuel.

Zijin County rubidium mineral is a granite type ore bodies with separate rubidium, tantalum and niobium are also associated rubidium ore body, the presence of mica in rubidium, see largest mine drilling thickness of over 500 meters, has reserves of 230,000 tons control rubidium, rubidium resource estimate 200 million metric tons, beneficiation experiments have higher recoveries; Jiaoling rubidium minerals, there are types of metamorphic sandstone and granite are two types, rubidium, mainly mica, feldspar present in the part, and see the largest drilling ore thickness over 650 m, rubidium estimated resources amounted to 1.6 million tons or more.

Experts pointed out that, as of now, the country identified a total of 19 mineral resource of 1.85 million tons of rubidium, but most is difficult to use. Guangdong Province two rubidium mineral resource estimates are large deposits of national standard 1000-fold and 800-fold, and a higher recovery rate, is prospecting breakthrough strategic action to achieve significant results.

At the meeting, the Guangdong Provincial Department of Public Rights Minister Wu stressed the need to continue to explore and accelerate the prospecting breakthrough; to strengthen rubidium far mine experiments and research, and constantly improve the recovery rate; to carry out the technical and economic assessment, for good economic returns; to properly handle the relationship between mineral exploration and ecological civilization construction, balanced, can be neglected.

Diode-pumped rubidium vapor laser light

Last May 18, the high-power electron gas by the laser technology developed by the Department of diode-pumped lasers rubidium vapor laser output. Diode-pumped rubidium vapor laser is a semiconductor laser-pumped alkali metal. Diode-pumped alkali metal vapor laser, the abbreviation DPAL (Diode Pumped Alkali Laser), refers to the use of a semiconductor laser as the pump source, pump cesium (Cs), rubidium (Rb), potassium (K), alkali metal vapor to produce laser. Laser class in 2003, proposed by the US Lawrence Livermore scientists, is a novel optically pumped gas lasers. It combines the high quality and good gas laser beam semiconductor laser small volumetric efficiency, thermal management problem is not prominent and other strengths, greater than 95% quantum efficiency at a wavelength of atmospheric transmission window for long-distance transmission, particularly well suited to high-power directional development, with a good prospect. Electronics, the semiconductor light pumped rubidium vapor laser with a wavelength of 780nm pulse width 1ms, 100Hz repetition frequency semiconductor laser as the pump light, the use of narrow line width grating pressure Narrowing the pump light technology to 0.2nm, by focusing after the incident on the rubidium vapor chamber by PBS. Rubidium vapor laser output wavelength of 795 nm, pulse power 18mW, linearly polarized fundamental mode laser.
