Abstract
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 microwatts per square centimeter. Switching is interpreted in terms of optical pumping into and out of the "dark" state.
