Taking radial and axial inhomogeneity of medium into consideration, we have obtained augmented transfer matrices and flow graph structures. As their applications we have studied the effect of air index gradient on laser alignment and the additional diffraction loss of laser caused by inhomogeneous pump. Results show that the axial index gradient can compensate the effect caused by radial index gradient in some cases.
