Tom-Michael Hesse,Barbara Paechrs couple optical fields via the radiation pressure of light. In this chapter, we provide a short history of study about optomechanical effects, and explain briefly about a part of optomechanical effects, e.g., cavity-assisted cooling, instability, measurement limit for continuous measurement, ponde

As for force measurements such as the GW detectors, in which the mechanical oscillator is used as a probe of external force, its sensitivity has almost been limited by the standard quantum limit (SQL). Also, theoretical analysis has proven to be a connection between rea
