We report the observation of laser induced birefringence (LIB) in awavelength-mismatched cascade system (J=0 \leftrightarrow J=1 \leftrightarrowJ=0 transitions) of inhomogeneously broadened ytterbium atoms with strong pumpand probe fields. We investigate the transmission spectrum of two circularpolarization (\sigma_p^+ and \sigma_p^-) components of strong probe field atfixed frequency, depending on the detuning of circularly polarized (\sigma_c^-)coupling field from two-photon resonance. We find that \sigma_p^+ (\sigma_p^-)polarized component exhibits a narrow electromagnetically induced absorption(transparency) spectrum. Numerical solutions of density matrix equations showqualitative agreement with experimental results. A Doppler-free dispersive LIBsignal is obtained by detecting the Stokes parameter of the probe field,enabling us to stabilize the frequency of coupling laser without frequencymodulation.Comment: 5 Pages, 3 figures, PDF file.
