N2 - Collisionless extraresonances (ER) in degenerate four-wave mixing (DFWM) are predicted when the upper state b of the ab transition, excited by near-resonant incident laser beams, decays to the lower state a both directly (ba) and via one or two intermediate states: bda or bcda. The width of the new ER, which depends on the relative decay rates in the cascade process, may be very narrow leading to very strong DFWM signals. Dephasing collisions affect the intensity of the new ER and also produce the usual, pressure-induced ER.
