We report on the resonant Fabry Perot cavity of the PVLAS (Po- larization of the Vacuum with LASer) experiment operating at λ = 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 x 10e5 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 (Po- larization of the Vacuum with LASer) experiment operating at λ = 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 x 10e5 m. The cavity length is 3.303 m, and the resulting finesse is 770 000.File in questo prodotto:
