Abstract
Power recycling was implemented on a fully suspended prototype interferomet er with arm lengths of 20 m. A wave-front-sensing technique for alignment c ontrol of the suspended mirrors was also implemented, which allowed for sev eral hours of stable operation. A power-recycling gain of greater than 12 w as achieved, a significant increase over the highest gain in a suspended mi rror Fabry-Perot Michelson interferometer reported to date.
