Abstract

A co-magnetometer gyroscope comprises a cell containing an alkali-metal and a noble-gas, the alkali-metal vapor being optically pumped with a pump laser circularly polarized and tuned to the D1 resonance, and a probe laser, linearly polarized and off- resonant, which passes through the cell perpendicular to the pump laser and measures the transverse component of the alkali-metal atoms spin polarization through optical rotation of the linearly polarized light, circuitry being provided suitable to dynamically change the optical pumping rate, thereby to obtain a high dynamic range.
