Abstract

For radiative processes involving two photons of different color in the limit when one of the photon frequencies is small, we show that the rate becomes very large due to a unique resonance. The two-photon rate becomes comparable with one-photon transition rates, even for low radiation field intensities. Applications of this phenomenon are discussed.
