A ring laser gyro scale factor enhancement circuit connected between at least one power supply voltage level and a reference potential for conditioning at least a first and second input signal from a ring laser gyro assembly, the first and second input signals being essentially sinusoidal and having a common first input signal frequency, the second input signal having a predetermined first phase relationship with the first input signal for a first ring laser gyro rotational sense and a second predetermined phase relationship with the first input signal for a second ring laser gyro rotational sense. The ring laser gyro scale factor enhancement circuit comprises at least one frequency multiplier circuit responsive to the first and second sinusoidal input signals at a first signal frequency for providing at least a first and second relatively sinusoidal output signal at a higher output signal frequency, the frequency of each first and second relatively sinusoidal output signal being a multiple of the integer two raised to a positive integer power times the common first input signal frequency of the first and second input signal; whereby, the ring laser gyro output signal scale factor is enhanced.
