Abstract
We observed radio-frequency (rf) induced transparency for a probe optical field in an rf-optical double resonance experiment in a neon discharge. The origin of the transparency is coherent population trapping at Zeeman sublevels of the lower level of an optical transition of neon. Stokes and anti-Stokes optical fields were generated due to stimulated Raman scattering of both the radio-frequency field on the probe-induced optical coherence and the probe field on the Zeeman coherence.
