The quadrupole transitions of ^<139> La nuclei around Pr^<3+> doped in LaF_3 have been detected as an optical-rf induced coherent Raman beat on the Pr^<3+>^3H_4-^3P_0 transition (20925 cm^<-1>) at 1.5 K.Because the effective ^<141>Pr nuclear magnetic moment is smaller in the excited ^3P_0 state than in the ground state, the Pr-La interaction decreases upon Pr^<3+> optical excitation, which makes the La quadrupole transitions couple with the Pr optical transition. Four magnetically inequivalent La nuclei were observed, revealing different local environments of La atoms around impurity Pr^<3+> ions.

LaF_3 中掺杂的 Pr^<3+> 周围的 ^<139> La 核的四极跃迁已被检测为 Pr^<3+>^3H_4-^3P_0 跃迁 (20925 cm^) 上的光学射频诱导相干拉曼拍频。 <-1>）在1.5 K。因为有效^<141>Pr核磁矩在激发^3P_0态比在激发态小在基态，Pr^3+光激发时Pr-La相互作用减弱，这使得La四极跃迁与Pr光学跃迁耦合。观察到四个磁力不等价的La核，揭示了杂质Pr^3+离子周围La原子的不同局部环境。
