Our topics

Maskless Poling of nonlinear-optical crystals

Periodically poled crystals are key components of many nonlinear-optical frequency converters, ranging from the visible spectral range up to the THz range. Fraunhofer IPM has developed a maskless poling technique that combines short turnaround times and full flexibility in poling-pattern design with high-quality poling results in materials like LiNbO3, LiTaO3 and BaMgF4.

Nonlinear-optical frequency conversion

Nonlinear-optical frequency conversion paves the way towards »tailor-made wavelengths« beyond the ranges of laser materials. Fraunhofer IPM has specialized in solutions for continuous-wave conversion.

Absorption spectroscopy of optical materials

High powers need high purities: The current development of high-power lasers calls for better quality assessment of optical materials for high-power applications and sensitive methods.
