Who invented sound laser

Because the waves emerging from a laser pointer are in sync, the beam can travel a long distance without spreading in all directions—unlike light from the sun or from a light bulb. In a standard optical laser the properties of the light output are controlled by the material from which the laser is made. Illustration of the silicon Brillouin laser in operation. The laser is formed from nanoscale silicon structures that confine both light and sound waves.

Yale scientists have created a new type of silicon laser that uses sound waves to amplify light. A study about the discovery appears in the online edition of the journal Science. Listen Up.

The new device could have significant and useful applications in the worlds of computing, imaging and even anti-terrorist security screening. The breakthrough, announced today, is detailed in this month's issue of the journal Physical Review B. Sasers had, until now, only been a theoretical concept. Albert Einstein laid the theoretical groundwork in for the invention of lasers, but the first working laser device wasn't created until
