Abstract: The sensitivity achieved by large ring laser gyroscopes opens the perspective to observe in an Earth-located laboratory extremely small effects expected from fundamental theories of physics. The next-generation sensor that could provide the required accuracy is a multiaxial heterolithic ring laser actively stabilized via a precise external diagnostic of circulating laser beams path. Here we report about the research activities and recent progress toward the development of a large frame He-Ne triaxial sensor with an ultimate accuracy of 10^{-11}, in order to detect the relativistic Lense-Thirring effect related to the Earth rotating mass. The actual activity is focused on the control of the systematic errors related to the fluctuation of the cavity geometry and the laser active medium parameters. In this work we will discuss in details only the first issue, to which my PhD studies are mainly dedicated.
