Crossing the threshold for laser cooling
(Phys.org) —Gallium nitride has emerged as one of the most widely used materials in the optoelectronics industry and the most important semiconducting material after silicon.
Controllable mode competition in a phonon laser
Using a novel realization of a "phonon laser," scientists at PML and the Joint Quantum Institute (JQI) have observed and learned to control a process called mode competition. This process occurs routinely ...
Researchers build fully mechanical phonon laser
Scientists examine possibility of a phonon laser, or 'phaser'
Quantum leap for phonon lasers
Physicists have taken major step forward in the development of practical phonon lasers, which emit sound in much the same way that optical lasers emit light. The development should lead to new, high-resolution ...
