We report the observation of three-mode optoacoustic parametric interactions of the type predicted to cause parametric instabilities in a 77-m -long, high-optical-power cavity that uses suspended sapphire mirrors. Resonant interaction occurs between two distinct optical modes and an acoustic mode of one mirror when the difference in frequency between the two optical cavity modes is close to the frequency of the acoustic mode. Experimental results validate the theory of parametric instability in...[Show more]
