A magnesium-oxide doped periodically poled lithium-niobate with segments of cascaded poling periods as a nonlinear crystal for intracavity frequency doubling of an optically pumped semiconductor disk-laser to the green spectral range is presented. Results show temperature-dependent second harmonic generation and a maximum output power of 62 mW at 525 nm corresponding to a 24% conversion efficiency.
