We propose and analyze a novel low-threshold amplification scheme by bichromatically coupling three upper states including a metastable state. We numerically show that it is possible to amplify VUV emission in Kr gases without population inversion at the probe transition. It is shown that the origin of low-threshold gain is the population trapping of upper states dressed by two intense coupling lasers, and there is a possibility of forming large population inversion in optically dressed systems.
