摘要：

We report the first observation of electromagnetically induced transparency (EIT) in an isotopically purified Nd3+: YLiF4 crystal. This crystal demonstrates inhomogeneous broadening of optical transitions of about 35 MHz. EIT is observed in a symmetrical Lambda-like system formed by two hyperfine sublevels of the ground state corresponding to a zero first-order Zeeman (ZEFOZ) transition and a hyperfine sublevel of the excited state, which is not coupled to other ground-state sublevels. It is found that transmission of the probe field as a function of the two-photon detuning demonstrates a comblike structure that can be attributed to superhyperfine coupling between Nd3+ ions and fluorine nuclei. The observed structure can be resolved only in the vicinity of the ZEFOZ point where the homogeneous linewidth of the spin transition is sufficiently small. The results pave the way for implementing solid-state quantum memories based on off-resonant Raman interaction without spectral tailoring of optical transitions.
