Frequency combs are now finding applications
far beyond the initial purpose. In particular, laser comb generators are
becoming powerful instruments for broadband molecular sensing and they create
new opportunities for multiplex nonlinear spectroscopy. Multi-heterodyne
dual-comb spectroscopy – a comb-enabled technique of Fourier transform
spectroscopy – demonstrates that the precisely spaced spectral lines of a laser
frequency comb can be harnessed for broad spectral bandwidth linear and
nonlinear spectroscopy, with much improved acquisition speed, precision and
accuracy. Some of the specific features of dual-comb spectroscopy will be
presented and selected applications to molecular spectroscopy where the technique
may be particularly useful will be discussed
