Abstract :
By stabilising a laser on the flank of a Doppler broadened iodine absorption line, a test bed for measuring the frequency stability performance of potential coherent communications lasers has been developed. The system can also be used to provide a compact platform for laser frequency stabilisation for use in free space coherent laser communications. The effects of temperature on system accuracy and drift measurements of a communications laser are also presented
