An experiment of second harmonic generation in a KNbO_(3) slab waveguide u reported.A power conversion efficiency of 11.3%and a slope efficiency of 17%have been obtained in a 93μm waveguide pumped by a Q-switched Nd:YAG laser.The oscillation output with increase of the beam diameter is due to the interference effect in waveguide.
