G&H’s Periodically Poled Lithium Niobate (PPLN) provides a highly efficient means of producing a range of IR wavelengths from currently available laser sources.

Periodically poling is a technique for achieving quasi-phase matched interactions in transparent crystal materials. By regularly reversing the sign of the effective nonlinear coefficient the phase mismatch introduced in one coherence length of material is “undone” in the next layer of material, and so on along the optical path. This technique can achieve high conversion efficiencies for relatively low power applications.

Fabricated and AR coated entirely at the facilities of G&H, these devices exhibit the same level of quality and performance typified by other G&H products.

Available in standard OPO configurations or custom patterns designed to meet specific requirements, G&H PPLN devices may be the answer to your application requirements.
