Quasi-phase-matching (QPM) has attracted much interest for second-harmonic generation (SHG). In this paper we present SHG experiments in periodically poled lithium niobate, fabricated through field poling via liquid electrodes. The experimental phase-matching bandwidth of a 3.3-mm bulk crystal was equal to the theoretically expected value, indicating that the domain inversion was uniform throughout the volume of the crystal.
