Abstract
It is predicted that, at sufficiently high laser intensity, the recently observed Raman-type extra-resonant enhancement of four-wave mixing [Y. Prior, A. R. Bogdan, M. Dagenais, and N. Bloembergen, Phys. Rev. Lett. 46, 111 (1981)] should not vanish in the absence of collisions. The collisionless contribution to the extra resonance is associated with a three-photon scattering process which produces an extra-resonant signal intensity which is fourth order in the laser intensity.Keywords
