We show that in the case of the BFKL pomeron with running coupling the diffusion pattern is strongly modified and is characterised by the sudden tunneling transition to the non-perturbative regime. We suggest that by using the b-expansion method one can suppress the non-perturbative Pomeron and isolate purely perturbative part of the gluon Green's function.
