A team of researchers working at the National Ignition Facility, part of Lawrence Livermore National Laboratory, has found that covering a cylinder containing a small amount of hydrogen fuel with a magnetic coil and firing ...
Israeli and German researchers have developed a way to force an array of vertical cavity lasers to act together as a single laser—a highly effective laser network the size of a grain of sand. The findings are presented ...
