The Nature Physics paper is entitled “A phonon laser.” Its authors are Kerry Vahala, Maximilian Herrmann, S. KnÃ¼nz, V. Batteiger, G. Saathoff, Theodor W. HÃ¤nsch, and Th. Udem.
For many years, scientists have wanted to find some way to build a phonon laser, one that emits “quanta of vibrational energy—so called phonons—instead of light.”
One important reason that such a phonon laser is needed in science is to dramatically increase the resolution within imaging techniques, such as tomography.
Consequently, the first ever creation of a phonon laser is the first step toward the accomplishment of this goal.
Dr. Theodor W. HÃ¤nsch, at the Max Planck Institute, and Dr. Kerry Vahala, at the California Institute of Technology (now working at MPI), led the team of scientists in this development of the phonon laser.
