7. Neglecting ωd terms in Eq. (4) implies a well behaved adiabatic solution of Eq. (2) and all waves travel with the same group velocity very close to c so that differences in propagation velocities are not important. It should be noted that Eq. (4) with both ωd terms kept can still be easily calculated numerically. By evaluating Eq. (4) in the region of -ε ≤ ω ≤ ε where ε 1 one can further examine the possible corrections due to velocity differences. This can provide useful insights on the possible extension of the present scheme to the ultraslow propagation regime using a very short medium so that peak separations between all FWM fields are still small.
