摘要
Numerical comparisons of the acceptance bandwidths for quasi-phase-matched (EZEZomega)-E-omega-E-Z(2omega) (ee-e) and (EYEYomega)-E-omega-E-Z(2omega) (oo-e) second-harmonic generation processes in bulk periodically poled LiNbO3 (PPLN) are given. The larger acceptance bandwidths and grating periods for the latter process lower the fabrication constraints, especially in the short-wavelength region, and also enhance the frequency conversion efficiency. The corresponding (oo-e) quasi-phase-matching conditions in bulk PPLN are discussed for different fundamental wavelength regions.
