Efficient cw 532 nm green-light generation is demonstrated using a periodically poled MgO : LiNbO 3 ridge waveguide prepared by a process that combines annealed proton exchange and precise dicing. Performance of waveguides with different widths has been investigated. The 6- μ m -wide, 1.6-cm-long uncoated ridge waveguide has achieved a green output power of 127 mW under a coupled fundamental light power of 250 mW . The highest conversion efficiency achieved is 53%.
