Abstract
Next generations of gravity missions require new technologies for an absolute frequency determination of cavity stabilized lasers. One proposed technology uses a readout of the free spectral range of the cavity to process it along with the mode number to the absolute frequency. This technology would require only a small amount of hardware but presupposes a stable mode number. In a laboratory experiment, this technology is analyzed for an existing high finesse cavity setup and the mode number is determined with an accuracy up to three digits. These measurements carry out a non-negligible fractional offset of α = 0.786 ± 0.003, where a part of γ = 0.69 is probably caused by the mirror coatings. For further investigation of how external influences can affect this offset, the plans for a new compact cavity setup which is designed precisely for these studies are presented here.
