Fraunhofer Institute for Physical Measurement Techniques IPMLasers are an indispensable tool for measurement technology and many other fields. However, the wavelength required are often not available off the shelf. In the »Photonic Systems« department, headed by Dr. Frank Kühnemann, we use nonlinear optical frequency conversion methods to produce customized wavelengths for a number of application areas. These methods primarily involve converting single-frequency continuous-wave laser light, the conversion efficiency and frequency stability requirements of which are particularly high.
Our services range from customer-specific nonlinear optical crystals for frequency conversion to the development of production-ready optical parametric oscillators prototypes for OEM laser manufacturers.
The light sources developed by Fraunhofer IPM are used in various fields, including quantum technology, nanophotonics, digital holography, Raman spectroscopy, fluorescence microscopy and the production of micro-optical diffraction elements.
