Ab Initio Frequency Measurement and Characterisation of Frequency Doubled Fibre Laser Utilised for Precision Oscillators

An ab initio measurement of a free running, frequency doubled erbium fibre laser is made with an optical frequency comb in concert with an internally calibrated wavemeter. The measurement is validated via a Monte Carlo uncertainty analysis. The operation and characteristics of a new high performance optical metrology source for an optical frequency standard is also verified in the process.
