A Smarter Way to Make Ultraviolet Light Beams

ANN ARBOR, Mich.— Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve information storage, microscopy and chemical analysis.

A paper on the research is newly published in Optics Express. The research was led by Mona Jarrahi and Tal Carmon, assistant professors in the Department of Electrical Engineering and Computer Science. The experiment was performed by Jeremy Moore and Matthew Tomes, both graduate students in the same department. (more…)

*Berkeley Lab physicists join with their international colleagues in reaching a new frontier in antimatter science*

The ALPHA Collaboration, an international team of scientists working at CERN in Geneva, Switzerland, has reported storing a total of 309 atoms of antihydrogen, some for up to 1,000 seconds (almost 17 minutes), with an indication of much longer storage time as well.

ALPHA announced in November, 2010, that they had succeeded in storing antimatter atoms for the first time ever, having captured 38 atoms of antihydrogen and storing each for a sixth of a second. In the weeks following, ALPHA continued to collect anti-atoms and hold them for longer and longer times. (more…)
