| Popis: | We operate a large helium–neon-based ring laser interferometer with single-crystal GaAs/AlGaAs optical coatings on the 2s2→2p4 transition of neon at a wavelength of 1.152276 μm. For either single longitudinal- or phase-locked multi-mode operation, the preferable gas composition for gyroscopic operation is 0.2 and 0.3 mbar of 50:50 neon with total pressures between 6–12 mbar. The Earth rotation bias is sufficient to unlock the device, yielding a Sagnac frequency of approximately 60 Hz. |
