Quasi-degenerate four-wave mixing (FWM) of low-intensity radiation (with an intensity less than 1 mW cm{sup -2}) was observed for the 5S{sub 1/2}(F=2)-5P{sub 3/2} (F'=3) transition in an optically transparent {sup 87}Rb vapour under conditions of electromagnetically induced absorption. The efficiency of frequency conversion was no less than 1% with respect to the intensity of pump waves. Nonlinear FWM is highly selective relative to the frequency detuning of pump waves (the FWM full width at half maximum was less than 50 kHz). (letters to the editor)
