Contrary to monolithic resonators, open Fabry-Perot cavities require in situ mode-matching of the cavity mode to external optics. This is a laborious and non-trivial task if a single emitter is used, as appreciable count rates can only be achieved for close-to-optimal coupling. To this end, we show that the Raman scattering from the solid-state host can be harnessed for in situ characterisation and optimisation of the cavity mode [2]. We demonstrate a 58.8-fold enhancement of the Raman transition compared to confocal measurements under similar conditions. Furthermore, replacing the detection optics with a CCD camera enables single-shot images of the modes’ lateral profile.
