We report on the resonant Fabry Perot cavity of the PVLAS (Polarization of the Vacuum with LASer) experiment operating at $\lambda = 1064$ nm with a record decay time of 2.7 ms, a factor more than two larger than any previously reported optical resonator. This corresponds to a coherence length of $8.1\cdot10^5$ m. The cavity length is 3.303 m, and the resulting finesse is 770 000.

Abstract

We report on the resonant Fabry Perot cavity of the PVLAS (Polarization of the Vacuum with LASer) experiment operating at $\lambda = 1064$ nm with a record decay time of 2.7 ms, a factor more than two larger than any previously reported optical resonator. This corresponds to a coherence length of $8.1\cdot10^5$ m. The cavity length is 3.303 m, and the resulting finesse is 770 000.
