The core competence of Peter
Tidemand-Lichtenberg's research is in the development of novel
light sources and detection systems targeted for specific
applications. The light sources and detector systems are based on
non-linear frequency mixing using efficient solid-state or
semiconductor based laser systems.
Specifically a generic approach is sought for the
development of coherent light sources in the UV and visible
spectrum. The light sources are designed and tailored for specific
applications, e.g. in terms of wavelength, tuneablilty, pulse
duration, and pulse energy. Applications are within
bio-medicine: e.g. as excitation light source for fluorescence
spectroscopy and within dermatology.
The spectral coverage from the visible has recently been
extended to cover the mid-IR spectral range, allowing for
development of efficient light sources as well as detection systems
in the 2 – 12 um range based on frequency
mixing. Applications for these systems are gas sensing: e.g.
in monitoring combustion systems or environment
control. Lately systems for hyper spectral imaging in the
mid-IR spectral range have been the main focus.
