An optical resonator can be used as a model system for the dynamics of the interaction of a single photon and a two-level system. Following this comparison, the energy stored inside the resonator is an analogue to the probability for absorption of the photon by the two-level system. Both systems respond in a similar way to the temporal profile of the incident light field [1]. For both, resonators and two-level systems, an optimized process is achieved by using an exponential rising pulse with a time constant matching the lifetime of the system. Using such an optimal pulse shape, the above mentioned processes reach an unit efficiency under idealized conditions.
In this contribution, we present experiments on coupling to a resonator and discuss the influence of various pulse shapes to the energy storage efficiency.
