HC Photonics

HC Photonics, founded in year 2000 by a team of Stanford graduates, is the pioneer of periodical poling (PP) technology and the technology leader today. HCP specialises in commercial volume production of periodically-poled nonlinear crystals (PPXX, PPLN, PPMgO:LN, PPMgO:LT) and fiber pigtailed mixers for various laser applications from UV to Mid-IR (355nm-5μm).

Combining this world-leading PP technology with extensive manufacturing experience,
HCP continues to position itself as a committed partner, working closely with customers to bring their ideas to fruition.

HC Photonics has a wide range of specifications available for these products over and above the standard options. Please contact us with your specific requirements so we can find the right product for you.

Periodically Poled Crystals and Modules

PPLN Enhanced Cavity Mixers

HCP offer a range of PPLN mixer configurations containing an optical cavity for enhanced conversion efficiency.


PPXX (periodically poling lithium niobate/tantalate) technology is an efficient laser wavelength conversion technology, which enables the generation and conversion of new laser wavelengths via a material's nonlinearity χ(2).
