摘要：
Off-axis Gaussian beam propagation through ABCD optical systems is analyzed using a relation between beam moments of irradiance in off-axis and on-axis propagation, respectively. Analytical expressions to link off-axis and on-axis Gaussian beam propagation parameters (for instance squared beam radius, Kurtosis and Skewness parameters) are obtained. It is shown that off-axis propagation causes an increase of beam waist radius, a decrease of beam symmetry and it may flat beam profile.
