| Zusammenfassung | We present a setup based on a low-vibration closed-cycle cryostat for the characterization of mirror coatings and for the direct measurement of Brownian thermal noise from room-temperature to 4 K. Using a dual frequency modulation scheme allows us to lock a laser to two eigenmodes of a high-finesse optical resonator simultaneously and to track the line splitting between the two modes. This facility will enable to investigate the temperature and power dependence of the birefringent line splitting and noise in AlGaAs/GaAs multilayer coatings across a broad temperature range. |
