The PVLAS experiment, running at the Legnaro National Laboratory of INFN (Padova, Italy), is operating a 6.4 m long, 10^5 finesse Fabry‐Perot (FP) cavity frequency locked to a 1064 nm, 100 mW output power Nd:YAG infrared laser. This cavity has a quality factor greater than 1012, and is kept at resonance for periods of time in excess of several hours. A 100 mW, 532 nm, laser has been recently locked to an 87 cm long FP cavity with a finesse of 45000. Light power density at the center of this resonator was 1200 W/cm^2. Short term plans of the PVLAS experiment foresee the installation of a 6.4 m long, 10^5 finesse, Fabry‐Perot resonator operating at 532 nm. Dedicated developments with a 532 nm, 5 W, input laser would provide a 10 kW/cm^2 power density, over a 1 cm^2 cross section, useful for laser assisted H− full stripping.

Abstract
The PVLAS experiment, running at the Legnaro National Laboratory of INFN (Padova, Italy), is operating a 6.4 m long, 10^5 finesse Fabry‐Perot (FP) cavity frequency locked to a 1064 nm, 100 mW output power Nd:YAG infrared laser. This cavity has a quality factor greater than 1012, and is kept at resonance for periods of time in excess of several hours. A 100 mW, 532 nm, laser has been recently locked to an 87 cm long FP cavity with a finesse of 45000. Light power density at the center of this resonator was 1200 W/cm^2. Short term plans of the PVLAS experiment foresee the installation of a 6.4 m long, 10^5 finesse, Fabry‐Perot resonator operating at 532 nm. Dedicated developments with a 532 nm, 5 W, input laser would provide a 10 kW/cm^2 power density, over a 1 cm^2 cross section, useful for laser assisted H− full stripping.
