Sound Laser
Two separate research groups, one located in the US and the other in the UK are reporting the development of a new type of practical phonon lasers that emit sound in much the same way that optical lasers emit light, a development that should lead to new, high-resolution imaging devices. Although the recent landmark breakthroughs are impressive, Phonon lasers have to go a long way to match the utility of their optical cousins. But the many applications that physicists have in mind already, including medical imaging, high precision measurement devices, and high-energy focused sound, suggest that sound-based lasers may have a future nearly as bright as light lasers.
