This work combines phase perturbation techniques with resonator oscillation formalism to describe the effect of the perturbation on the beam quality of the laser radiation field. The scattering terms of the perturbation are computed to the second order and are used to determine the mode intensity ratios (MIR) and the Strehl ratios. The MIR and Strehl ratios are computed for the simple case of symmetric flat disk undergoing a symmetric linear tilt.
