Abstract
Precision spectroscopy on molecular tellurium is performed by measurin g the frequency difference between the observed lines and an eigenfreq uency of a high-finesse cavity mode. The mode frequency is derived fro m a measurement of the cavity's free spectral range taking into accoun t the cavity dispersion due to phase shifts in the dielectric mirror c oatings. The experimental technique is based on dual frequency modulat ion and is applied to determine the transition wavenumbers of several lines in Te-130(2) near 467 nm with an uncertainty of 2 x 10(-8).
