A new method of anti-Stokes Raman conversion termed dual-wavelength pumped Raman- resonant four-wave mixing, where a relatively intense secondary pump is applied in the phase- matched direction to enhance anti-Stokes conversion of a main pump, is proposed. Conditions for optimizing the conversion efficiency are also investigated. A remarkable feature of this method is that the optimum conversion efficiency is independent of the initial intensity of the main pump. It has been shown that nearly 60% of anti-Stokes conversion efficiency is theoretically possible in the vacuum ultraviolet region.
