Optical Frequency Synthesis Based on Modelocked Lasers



S T. Cundiff, Jun Ye, John L. Hall


The synthesis of optical frequencies from the primary cesium microwave standard has traditionally been a difficult problem due to the large difference in frequencies. Recently a dramatic advance in this field has occurred due to the introduction of the use of modelocked lasers. This has been particularly aided by the ability to generate modelocked spectra that span an octave. This review article describes how modelocked lasers are used for optical frequency synthesis and recent results obtained using them.
