Engineering the output power of a one-atom laser

Hybrid systems combine elemental components with distinct tunable properties, offering a way to explore novel mechanisms of coherent energy exchange. Here, we have considered a resonator that starts to oscillate when electrons with fixed spin are injected from electrical contacts to a quantum dot, realising a highly-efficient single atom laser. We have shown that the common theoretical tool to describe the laser — the rotating-wave approximation — becomes insufficient, because a large...
