Abstract

Electromagnetically induced transparency (EIT) resonances using the 5rm{S}1/2→5rm{P}3/2→5rm{D}5/2 ladder-system in optically thick Rb atomic vapour are studied. We observe a strong line narrowing effect and gain at the 5rm{S}1/2→5rm{P}3/2 transition wavelength due to an energy-pooling assisted frequency conversion with characteristics similar to four-wave mixing. As a result it is possible to observe tunable and switchable transparency resonances with amplitude close to 100\% and a linewidth of 15 MHz. In addition, the large line narrowing effect allows resolution of 85Rb 5rm{D}5/2 hyperfine structure even in the presence of strong power broadening.
