Frequency comb technology uses a unique combination of broadband optical coherence and unprecedented frequency stability to create new tool for active and passive sensing and metrology.  Recent developments utilize this precision to demonstrate orders of magnitude improvement over state of the art spectroscopy, long distance ranging and velocity measurement, frequency conversion, and timing transfer.

Demonstrations in comb-based high precision optical metrology for remote sensing systems are presented along with progress of an all fiber comb system being developed for spaceflight at Ball Aerospace.  Further near term applications for Ball’s frequency comb include long distance nanometer precision ranging and femtosecond jitter timing transfer are discussed.
