However, by controlling an instability that causes the transfer of energy when beams cross, the researchers were able to combine the energy from multiple beams into a single powerful beam. (llnl.gov)
The new microendoscope is based on a multimode optical fiber, which can carry different multiple beams of light at the same time. (sciencedaily.com)
In contrast, phased - array radar sends out multiple beams simultaneously, eliminating the need to tilt the antennas, decreasing the time between scans of storms to less than a minute. (scientificamerican.com)
