Abstract

We present high resolution measurements of Doppler free features within Rubidium (Rb) filled photonic crystal hollow core fibre (HC-PCF). Measurements within a Rb filled fibre with core diameter of 35μm show broadening of only 1 MHz associated with the transit time effect. This low level of additional broadening opens the door to compact frequency standards. We present initial spectroscopy of the narrow Rb 5S→5D two-photon transition within the fibre which we will use to create a compact frequency standard. © 2011 IEEE.
