Stalnaker and Vladislav Gerginov and Scott Diddams}, title = {Direct frequency comb spectroscopy}, abstract = {Besides serving as a frequency counter or clockwork, an optical frequency comb can be used directly for spectroscopy, thus the name Direct Frequency Comb Spectroscopy (DFCS). Precise phase coherence among successive ultrashort pulses allow one to explore both fast dynamics in the time domain and high-resolution structural information in the frequency domain. Coherent accumulation of weak pulses can lead to strong field effects. Combined with spectral manipulation, high-resolution quantum control can be implemented. The large number of frequency comb components also provide a massive set of parallel detection channels to gather spectroscopic information. In this chapter we provide a detailed review of some of the current applications that exploit these unique features, and discuss several future directions of DFCS.}, year = {2008}, journal = {Advances in Atomic, Molecular, and Optical Physics}, volume = {55}, chapter = {1}, pages = {1-60}, month = {2008-02}, publisher = {Elsevier}, issn = {1049250X}, isbn = {9780123737106}, url = {https://www.sciencedirect.com/science/article/pii/S1049250X07550019?via%3Dihub}, doi = {10.1016/S1049-250X(07)55001-9}, }
