Green PPLN chips are designed for green light generation at 532 nm based on second harmonic generation (SHG). The generated green light has important applications such as laser display and bio-instrumentation. We provide 5 mol% MgO doped congruent PPLN chips in a form of both bulk and waveguide, which have features such as high optical damage threshold and high efficiency
