Nonlinear Optics

In the Working Group Optical Technologies, optical parametric generators, amplifiers and oscillators are used to provide tunable light sources in the near- to mid-infrared wavelength range for non-linear Raman microscopy and other spectroscopic fields of application. These frequency converters are typically pumped with ultrafast laser beam sources (see section laser physics).

In addition to the exploration of new wavelength ranges, the group is doing research on the generation and control of supercontinua as well as new optical switches by means of the conversion of transversal modes (see section light conversion in waveguides).
