High-sensitivity optical measurement of mechanical Brownian motion

High-sensitivity optical measurement of mechanical Brownian motion

Europhys.Lett.46:545-551,1999 We describe an experiment in which a laser beam is sent into a high-finesse optical cavity with a mirror coated on a mechanical resonator. We show that the reflected light is very sensitive to small mirror displacements. We have observed the Brownian motion of the reson...

Zusammenfassung:Europhys.Lett.46:545-551,1999 We describe an experiment in which a laser beam is sent into a high-finesse optical cavity with a mirror coated on a mechanical resonator. We show that the reflected light is very sensitive to small mirror displacements. We have observed the Brownian motion of the resonator with a very high sensitivity.
