The investigation of the infrared behavior of the propagator of a light wave in a randomly inhomogeneous medium with massless Gaussian noise is continued. The infrared representation of the propagator for correlation function D/sub /var phi//(k)/approximately/k/sup /minus/2/ is generalized to the case of an arbitrary power-law noise correlation function is rigorously established in the first two orders of the infrared asymptotic behavior by construction of a suitable R operation. As a consequence, the results are generalized to the case of critical opalescence, when D/sub /var phi//(k)/approximately/k/sup /minus/2+/eta//, where /eta/ /sup /approximately// 0.03 is the Fisher index.
