Abstract

We have observed negative optical torsional rigidity in an 80 m suspended high optical power cavity that would induce the Sidles-Sigg instability as a result of sufficient circulating power. The magnitude of the negative optical spring constant per unit power is a few μN m/W as the result of the optical torsional stiffness in the yaw mode of a suspended mirror Fabry-Ṕrot cavity. It has been observed to depend on the g -factor of the cavity which is in agreement with the Sidles-Sigg theory.
