The research may pave the way to systems that allow audible messages to be transmitted to spies or other agents, warning them of impending danger like an active shooter. 'Whisper' laser tech sends ...
It consisted of a microphone in one location and a remote listening post with a speaker that could also be recorded using a phonograph. While also marketed as a device that allowed broadcasting of sounds, or dictating text from one room to a typist in another, it was used in several criminal investigations. [8] [9]

[5]: 88 [21] As a result of this success Maiman persuaded Hughes management to use company funds to support his laser project beginning in mid-1959. On a total budget of $50,000, Maiman turned to the development of a laser based on his own design with a synthetic ruby crystal, which other scientists seeking to make a laser felt would not work.
There's no magic to text messages, no "secret sauce" that makes them especially dangerous. They work because people are less likely to be wary of a text than an email, period. So be wary.
On 25 August 2009, U.S. patent 7,580,533 was issued for a device that uses a laser beam and smoke or vapor to detect sound vibrations in free air ("Particulate Flow Detection Microphone based on a laser-photocell pair with a moving stream of smoke or vapor in the laser beam's path"). Sound pressure waves cause disturbances in the smoke that in ...
The laser’s fast data downlink speeds are comparable to broadband internet, and the DSOC team recently downloaded 1.3 terabits of data in one evening — comparable to the 1.2 terabits sent back ...
