Continuous-Wave Superradiant Diamond Maser

Objectif

We propose to realise the first continuous-wave superradiant maser in a solid-state system at room temperature, a fundamentally new class of microwave source whose coherence is stored collectively in a spin ensemble rather than defined by a resonator, making it intrinsically immune to the thermal noise that limits conventional room-temperature oscillators. By coupling nitrogen-vacancy (NV) centres in diamond to a microwave cavity in the bad-cavity regime, the emitted radiation achieves linewidths orders of magnitude below the cavity linewidth, with frequency stability set by spin coherence rather than cavity losses, a critical advantage at microwave frequencies where thermal photon occupation is large. The project builds directly on our group's demonstrations of pulsed superradiance, long-lived inversion storage, and self-induced quasi-continuous masing (Nature Physics, 2026), and on a preliminary CW prototype that has already confirmed all essential physical primitives but remained below threshold. Newly available high-coherence diamond materials are projected to bring sustained CW operation within reach. Within 18 months, we will implement compact 3D lumped-element cavity architectures with fibre-integrated optical pumping and establish room-temperature continuous superradiant emission, delivering a prototype with characterised linewidth, frequency stability, and magnetic-field sensitivity. The outcomes open a direct pathway to compact quantum magnetometers, portable microwave frequency references for precision metrology, and coherent microwave sources for quantum hardware. Looking further ahead, our work establishes the operating principles for a broad platform of solid-state superradiant emitters (alternative dopants and novel host materials) which will allow to expand superradiant sources from the microwave domain into the THz regime.
