Robust, wavelength- and temperature-insensitive 14 krad/s endless polarization tracking over 2.5 Grad

Results of 14 krad/s endless polarization tracking experiments are presented. Wavelength (1520...1564 nm), temperature (0...70degC) and second, nominally fixed polarization were varied, and a 2.5Grad long polarization trajectory was tracked in 64 h. Mean/maximum polarization errors were les0.053/0.13 rad.
