| Description | We have demonstrated a 650 GHz saser (sound laser) device based on the working principles of a THz quantum cascade laser in an acoustic cavity. We have observed an increased of the directionality of the emitted sound undes sasing conditions. |
| Exploitation Route | By conducting further research to study the acoustic emission spectrum. |
