We show theoretically that by applying a bichromatic electromagnetic field, the dressed states of a monochromatically driven two-level atom can be pumped into a coherent superposition termed dressed-state coherent population trapping. This effect can be viewed as a new key to manipulating a two-level system via its control over dressed-state populations. Applying this effect in the precision measurement of Rabi frequency, the unexpected population inversion and lasing without inversion is discussed to demonstrate such controllability.
