Abstract
An iodine vapour loaded hollow core photonic crystal fibre (HC-PCF) and a traditional iodine cell were used to perform spectroscopy and frequency stabilisation .The low power line width of the iodine sub-Doppler hyperfine feature was 5.2±0.3MHz in the cell, and 6.0±0.3MHz in the HC-PCF. A Nd:YAG laser was frequency stabilised to a sub-Doppler iodine hyperfine feature using wavelength modulation. The iodine loaded HC-PCF system achieved a shot-noise limited fractional frequency stability of2.3x10-12 at 1 s, almost an order of magnitude better than the prior state of the art fibre based laser stabilisation system at the time of publishing.
