Abstract
Optical frequency comb systems have received much attention in recent years due to their enormous potential in optical frequency metrology and optical frequency synthesis applications. The expected transition to optical time standards, attosecond lasers and optical electron accelerators will all rely on the availability of rugged and stable frequency comb lasers, combining superior performance with utility. Fiber laser based frequency combs have a number of advantages over their Ti:sapphire cousins in that they are more compact, are capable of turnkey, long-term operation with power consumption, are compatible with existing fiber optics, and cover the telecommunication window. The first fiber-frequency comb systems showed excellent long-term performance but the short term performance was inferior to Ti:sapphire combs due to excess noise contribution. However, recently it was shown that the linewidth of the individual comb limes of a fiber frequency comb can reach the sub-Hertz level and fiber frequency combs are now approaching the performance of Ti:sapphire based systems.
