Recently it has been shown that parametric instabilities may significantly affect the perfomance of high power signal recycling gravitational wave interferometers such as the planned Advanced LIGO. We propose an experiment utilizing the optical spring effect to determine the likelihood of parametric instability. A mechanical resonator has been designed to maximize parametric instability with R-0 = 500. We show that cold damping will reduce the quality factor to similar to1000 while the rigidity is increased to similar to1500 N m(-1).
