Using coherence enhanced nonlinear optics we observe absorptive switching in hot Rubidium atoms. Electromagnetically induced transparency helps create a larger absorptive Kerr nonlinearity enabling strong absorptive switching with laser intensities of 10 μW/cm2. Switching is interpreted in terms of optical pumping into and out of the "dark" state.
