Systems and methods for improved ring laser gyroscope devices through mix ratio optimization

摘要

Systems and methods for improved ring laser gyroscope devices through mix ratio optimization are provided. In one embodiment, a ring laser gyroscope device comprises: a laser block assembly having a cavity therein that defines a ring shaped laser beam path around the laser block assembly, the cavity containing a fill gas mixture comprising Helium and Neon, wherein the laser block assembly is characterized as having a Neon depletion life limiter; and a readout assembly optically coupled to the laser block assembly. The readout assembly outputs a laser intensity monitor (LIM) voltage that represents optical energy within the cavity. The fill gas mixture has a Helium to Neon ratio richer in Neon than a ratio that would produce a peak LIM voltage from the readout assembly.
