Prof. Dr.-Ing. Philipp Huke

 

My work is dedicated to experimental physics and optical engineering.
In the field of experimental astrophysics I am working with with an experimental team of about 10 people in the group of Prof. Reiners. The main aim is the development of (optical) frequency standards for the spectral observation of stars .

Calbiration of spectrographs can be done using gas cells (Iodine), calibrated lamps, Fabry-Perot etalons or frequency combs. Currently, in the optical laboratories of the institute all these technologies are under development. My actual work is focused on the stabilization of diode lasers which can be used for observing drifts of Fabry-Perot etalsons. With a high-resolution Fourier-Transform-Spectrometer (FTS) which will be calibrated with a frequency comb we are able to compare the different technics with a very high precision.
