Name of light source:Continuous-Wave Frequency Comb Fourier Transform Source based on a High-Dispersion Cavity
Name of vendor selling or name of group using this source:Sanders group, UW-Madison
Year of initial publication or catalog entry:2006
Primary application for which this source was developed:Absorption Spectroscopy
References or URLs for relevant information on this source:Th. Kraetschmer, J. W. Walewski, and S. T. Sanders, "Continuous-Wave Frequency Comb Fourier Transform Source based on a High-Dispersion Cavity", Optics Letters, accepted (2006)
Additional information / notes:Beating of nearby modes of an unequally spaced frequency comb naturally assigns unique amplitude modulation frequencies to each spectral component emitted. The source contains no moving parts.
