Abstract
A Cavity-Enhanced Direct Frequency Comb Spectroscopy (CE-DFCS) setup developed in our laboratory is described. We focus on the broadband spectrometer which is based on a Virtually Imaged Phased Array (VIPA). It can detect 3500 independent channels simultaneously, covering a bandwidth of 20 nm with a resolution of 800 MHz around a central frequency of 1.5 μm in a few microseconds. The bandwidth can be extended to 200 nm by rotating the grating of the VIPA spectrometer.
