Open-access microcavities: high stability without dedicated mechanical low-pass filter in closed-cycle cryostats

M. Fisicaro, M. J. Rost, M. Witlox +2

Open-access optical microcavities are Fabry-Perot type cavities consisting of two micrometer-size mirrors, separated by an air (or vacuum) gap typically of a few micrometers. Compa…
