摘要：
We report the experimental study of seeded and noise initiated modulational instability (MI) during second harmonic generation in a LiNbO3 slab waveguide. In the non-seeded case, two MI initiating mechanisms were identified, namely random noise on the input beam and waveguide imperfections. We also measured the MI gain coefficient as a function of periodicity and beam intensity employing a small, well-defined periodic perturbation (seeding). Excellent agreement with theory was obtained.
