Optical control is essential for efficient single-photon generation in quantum technology applications. The Swing-UP of Quantum EmitteR population (SUPER) mechanism is an approach to coherently control a quantum emitter by using two detuned laser pulses. Recently, SUPER has been extended to a fully quantized picture where two detuned cavity modes replace the pulses. Here we consider a different variation of SUPER where a single detuned laser pulse drives a quantum emitter coupled to an off-resonant cavity. As only one laser is needed compared to the original proposal, we term this the Single-pulse SUPER scheme. Using a dressed-state picture we explain the numerically observed dynamics and resonance conditions. We demonstrate that a high population inversion is theoretically feasible even when realistic cavity losses and emitter relaxation processes are taken into account. In addition to preparing the emitter in the upper state a photon is stored in the cavity. Thus, after completing the preparation a single photon is emitted by de-exciting the emitter and a second spectrally distinct single photon can be released from the cavity. These insights suggest that this system could be a source of two distinct single photons paving the way for a broad range of photonic applications.
