large variations of the surface stiffness. Here the optical restoring force comes from the dependence of the optical power, and hence the radiation pressure force, in the resonator on the resonator detuning [...] detuning, and hence the position of the cantilever. The student will implement the optical resonator, the optical coupling and readout. The parameter range in terms of oscillation frequency and quality factor [...] be driven. The driving is done via the process of parametric amplification, which requires a precise timing of the driving motor with respect to the actual pendulum motion. At the moment the timing is derived
