Stability of a high-finesse optical cavity at 493 nm in vacuum for cavity QED with Barium ions

Diptaranjan Das, Ezra Kassa, Hiroki Takahashi

We explore the stability of a high-finesse optical cavity at 493 nm in vacuum for cavity QED with Barium ions. A high-finesse Fabry-Perot cavity is built using mirrors with high-re…
