This CD Laboratory is concerned with research into novel coatings for mirrors in the field of laser spectroscopy. The aim is to analyse the properties of this crystalline mirror technology in detail and thus massively expand its range of applications.
One area of application for these mirrors is spectroscopy in the mid-infrared range using frequency combs. A frequency comb behaves like many thousands of highly stable continuous wave lasers, whereby each of the several thousand "teeth" of the comb corresponds to a laser with its own very stable wavelength. A frequency comb is generated by the high-precision stabilisation of a broadband laser pulse. In this CD Laboratory, the spectral range of frequency comb technology is to be shifted towards longer wavelengths in the mid-infrared. Until now, it has been very difficult to penetrate this wavelength range due to the lack of correspondingly high-quality optics.
Specific applications of these technologies include the detection of impurities in the Earth's outer atmosphere, the detection of biomarkers of certain diseases, the investigation of large molecules in their gaseous aggregate state and experiments to detect gravitational waves.
