In this talk, I will highlight some of the new laser tools and synthesis
applications being pursued at NIST in Boulder. This includes simple, table-top
approaches to generate frequency combs with brightness and bandwidth that rival
the infrared spectrum available from a synchrotron. These new infrared combs
are being used to explore opportunities in molecular fingerprinting and
microscopic spectro-chemical identification. In addition, I will describe our
advances in light synthesizers based on parametric oscillation in low-loss
microresonators, that now enable phase-coherent microwave-to-optical frequency
synthesis on a photonic-integrated-chip. Finally, I will provide an update on a
new 30 GHz near-infrared electro-optic frequency comb that has been running
continuously for the past six months at the McDonald Observatory where it is
being used with the Habitable Zone Planet Finder to search for exoplanets
around nearby M-dwarfs, the most prevalent class of stars in our galaxy.
