A high-power gas dynamic-laser example system is described, and its optical elements are represented in the ABCD-matrix formalism of Gaussian optics. Propagation of Gaussian beams, image formation, focusing, and steering by transverse refractive-index gradients are modeled with the ABCD matrix technique. The effects of small translations and rotations of optical elements are represented as matrices and vectors in the ABCD-matrix formalism, and are analyzed as component misalignments with single and multiple beam reflections. Example calculations show that alignment beams making multiple round trips inside an unstable resonator can easily provide satisfactory resonator alignment and designation of the aim point of an output optical train.
