Abstract: The results of experimental and theoretical investigations of the electromagnetically induced transparency regime on the ⁴ I _9/2-⁴ G _5/2 transition in Nd³⁺ ions doped in LaF₃ are presented. The superhyperfine splitting of the upper and lower working levels has been determined on the basis of the results obtained. A theoretical model adequately describing the parameters of the resonances of electromagnetically induced transparency has been developed by analyzing the experimental data.
