An electrically injected solid-state surface acoustic wave phonon laser

Nature, Published online: 14 January 2026; doi:10.1038/s41586-025-09950-8A completely solid-state, single-chip, microwave-frequency surface acoustic wave phonon laser can generate coherent phonons from thermal noise or resonantly amplify injected phonons using only a direct current bias field.
