The US Navy successfully tested its new laser weapon mounted on a warship. The dramatic photo above depicts the High Energy ...
During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...
Surface acoustic wave (SAW) filters already fill our mobile devices, but a new breakthrough finds a way to make them smaller, potentially leading to even more compact devices.
