In one embodiment, a method is provided. The method comprises transmitting a first laser pump signal to an optical resonator; adjusting a frequency of the first laser pump signal; generating a first order Stokes signal from the first laser pump signal in an optical resonator; measuring a first beat signal frequency; ceasing transmission of the first laser pump signal to the optical resonator; transmitting a second laser pump signal to the optical resonator; adjusting a frequency of the second laser pump signal; generating a first order Stokes signal from the second laser pump signal in the optical resonator; and measuring a second beat signal frequency; ceasing transmission of the second laser pump signal to the optical resonator.

A ring laser gyroscope (RLG) block is provided. The RLG block includes a first corner bordered by a first portion of a first side and a first portion of a third side; a second corner bordered by a first portion of a second side and a second portion of the third side; and a third corner bordered by a second portion of the second side and a second portion of the first side. The first portion of the first side shifts the first corner laterally in a lasing plane of the RLG block, toward the second corner, and perpendicular to a first normal of a first mirror when a temperature change contracts the RLG block; and shifts the first corner laterally away from the second corner, and perpendicular to the first normal when the temperature change causes an expansion of the ring laser gyroscope block.
