Abstract

Doppler-free spectroscopy of gases in hollow-core fiber (HCF) -based cells can be used for realizing new compact, robust and portable frequency standards. In this summary a method for cancelling interferences resulting from splices between standard telecom fiber and HCF using two piezoelectric stack actuators is presented. Both HCF and mirror-side standard fiber are modulated by stretching. The performance of the cancellation scheme was tested with a HCF yielding 99 % interference amplitude reduction.
