This has been a good week for sonic physics. First came reports that scientists used sound waves to create a sonic black hole. Now, it seems that a different group of scientists have used specially calibrated sound waves to create something almost as cool: a sonic laser. The lasers most people are familiar with are formed from beams of light with identical wave structures, added together to form one giant, coherent wave. The saser, created by scientists from the University of Nottingham, England, works the same way, but with correlated sound waves instead of light waves. read more
