Photonic Systems

Lasers are an indispensable tool in measurement technology and many other fields. However, wavelengths are often needed that are not available »off-the-shelf«. We use methods based on nonlinear optical frequency conversion to generate such wavelengths tailored for various applications. In this context, we focus on the conversion of single-frequency continuous-wave laser light, which places particularly high demands on the conversion efficiency and frequency stability.

Our services range from customer-specific nonlinear optical crystals for frequency conversion to the developmet of production-ready prototypes of optical parametric oscillators for OEM laser manufacturers. 

Light sources developed at Fraunhofer IPM are used in various applications, including quantum technologies, nanophotonics, (digital) holography, Raman spectroscopy and fluorescence microscopy. 

Examples of our solutions
