We report numerical simulation of conversion efficiency and beam quality factor ($M^{2}$) in second harmonic generation taking into account diffraction and pump depletion. Compared with the results in Boyd and Kleinman's study [J. Appl. Phys. 39 (1968) 3597], which treated the no-depletion case, with the presence of pump depletion, conversion efficiency is maximized under substantially weaker focusing. Depletion also leads to the degradation of the beam quality factor of both the unconverted fundamental and the generated second harmonic radiation.
