Abstract
Ultralow loss concave micromirrors with radii of curvature below 60 um were fabricated by laser ablation and reflective coatings. A 10 um long microcavity with a mode volume of 40 um^3 was set up with two such mirrors and the cavity linewidth measured both spectrally and temporally. The smallest linewidth obtained was 96 MHz, corresponding to a quality factor of 3.3x10^6 and a mirror finesse in excess of 1.5x10^5. With these parameters we estimate that a variety of solid-state quantum emitters coupled to the cavity may enter the strong coupling regime.Citation
