  We report electromagnetically induced transparency for the D1 and D2 lines in
$^{6}$Li in both a vapour cell and an atomic beam. Electromagnetically induced
transparency is created using co-propagating mutually coherent laser beams with
a frequency difference equal to the hyperfine ground state splitting of 228.2
MHz. The effects of various optical polarization configurations and applied
magnetic fields are investigated. In addition, we apply an optical Ramsey
spectroscopy technique which further reduces the observed resonance width.
