Sound amplification by stimulated emission of radiation of the laser. In a SASER device, a source (e.g., an electric field as a pump) produces sound waves (lattice vibrations, phonons) that travel through an active medium. In this active medium, a stimulated emission of phonons leads to amplification of the sound waves, resulting in a sound beam coming out of the device. The sound wave beams emitted from such devices are highly coherent. The first successful SASERs were developed in 2009. Instead of a feedback-built wave of electromagnetic radiation (i.e., a laser beam), a SASER delivers a sound wave. SASER may also be referred to as "phonon laser",
There's a New Sound never "kid themselves properly (or) let their voices go") by making appearances on "The Ernie Kovacs Show" and recording a full-length album, "Music to Suffer By", in the same style she used for "Fish." "There's a New Sound" was later featured often on the Dr. Demento show and performed by Scooter on "The Muppet Show". There's a New Sound "There's a New Sound" was a 1953 novelty song by Tony Burrello and Tom Murray. Burrello, a songwriter and jazz pianist, and Murray started writing novelty songs after they were unsuccessful in having their more serious-minded songs recorded by prominent musicians.
