Coherent Frequency Combs for Spectroscopy in the 3-5 Micron Region

April 18, 2017
Author(s):
Daniel I. Maser, Gabriel G. Ycas, William I. Depetri, Flavio Caldas da Cruz, Scott A. Diddams
A tunable mid-infrared frequency comb was created via diff erence frequency generation. Pulses between 1 and 1.5 μm were mixed to make idlers of 2.6-5.2...

Adaptive Terahertz Dual Frequency Comb Spectrometer

December 26, 2016
Author(s):
Flavio Caldas da Cruz, Francisco S. Vieira, David F. Plusquellic, Scott A. Diddams
Terahertz dual frequency comb spectroscopy (THz-DFCS) yields high spectral resolution without compromising bandwidth. Nonetheless, the resolution of THz-DFCS...
