ABSTRACT
The electromagnetically induced transparency (EIT) observations in two Λ-systems of 87Rb atom, and
have been investigated in detail and the results are found consistent with our proposed theoretical models. The second Λ-system provides EIT signal with higher magnitude than the first system, both in the absence and in the presence of an applied magnetic field. The observed steeper slope of the EIT signal in the presence of the magnetic field can enable one to achieve tight frequency locking of lasers using these EIT signals.
