摘要
We theoretically investigate several parameters for the nuclear magnetic resonance gyroscope based on ^(133)C_(s–)^(129)Xe/^(131)Xe. For a cell containing a mixture of ^(133)Cs at saturated pressure, we investigate the optimal quenching gas(N_2) pressure and the corresponding pump laser intensity to achieve 30% ^(133)Cs polarization at the center of the cell when the static magnetic field B0 is 5 μT with different ^(129)Xe/^(131)Xe pressure. The effective field produced by spin-exchange polarized ^(129)Xe or ^(131)Xe sensed by ^(133)Cs can also be discussed in different^(129)Xe/^(131)Xe pressure conditions. Furthermore,the relationship between the detected signal and the probe laser frequency is researched. We obtain the optimum probe laser detuning from the D2(6~2S_(1/2)→ 6~2P_(3/2)) resonance with different ^(129)Xe/^(131)Xe pressure owing to the pressure broadening.
