  • The Electromagnetically Induced Transparency(EIT) in crystals doped with rare-earth ions was researched. By taking a Er3+: YAG crystal for a sample, the probe field absorption as a function of the concentration of Er3+ ions was calculated by using density matrix equations in rotating-wave approximation. It indicates that when the detuning of the probe field p is 0, the transparency window of a probe field is generated, which demonstrates the feasibility to achieve the EIT in crystals doped with rare-earth ions. Furthermore, an excitation scheme for Pr3+: Y2SiO5 was performed, and it experimentally exhibits that when the temperature is 6 K, a 100% transparency window in the resonant absorption peak is formed in the absorption spectrum of Pr3+: Y2SiO5, and the EIT phenomenon in crystals doped with rare-earth ions is realized. In addition, the dependence of temperature and coupling field detuning on the EIT was presented. It is found that when the temperature increases to 15 K, the transparency window disappears, while the detuning of coupling field becomes larger and the transparency window gets smaller.
