Quasi-phase-matched second harmonic generation(SHG) in bulk periodically poled L iNbO3(PPLN) was studied , the coupled-wave equations for quasi-phase- matched S HG was accurately resolved, and the formula for calculating SHG conversion effic iency under focusing Gauss beams was given. The relations between focusing beams waist and crystal length were analyzed. Furthermore, the SHG cavity was opti mized to obtain the maximum conversion efficiency.
