The technique of frequency-comb Fourier transform spectroscopy [1-2], and especially dual-comb spectroscopy [3-6] is capable of extremely fast data acquisition combined with superior spectral resolution and broadband spectral coverage. The development of the dual-comb spectroscopy in the mid-IR was not as dramatic as in the near-IR, because of lack of sufficiently broadband and mutually coherent sources.<\/p><p align=\"justify\">In our group, we pioneered a new platform for mid-infrared dual-comb Fourier-transform spectroscopy. It is based on a pair of ultra-broadband subharmonic optical parametric oscillators (OPOs) pumped by two phase-locked thulium-fibre combs. Such OPOs operating at degeneracy are ideal coherent frequency dividers whose output is inherently frequency- and phase-locked to the pump [7-12]. The \u2018instantaneous\u2019 spectrum of frequency combs produced via subharmonic generation can be well above an octave [12]. Our dual-comb spectroscopy system provides fast (7 ms for a single interferogram), moving-parts-free, simultaneous acquisition of 350,000 spectral data points, spaced by 115-MHz intermodal interval over the whole 3.1\u20135.5 \u00b5m spectral range. Parallel detection of 22 trace molecular species in a gas mixture, including isotopologues containing such isotopes as 13C, 18O, 17O, 15N, 34S, 33S and deuterium, with part-per-billion sensitivity and sub-Doppler resolution has been demonstrated [13]. The technique also features:<\/p><ul><li>absolute optical frequency referencing to atomic clock,<\/li><li>high degree of mutual coherence between the two mid-infrared combs\u00a0 with a relative comb-tooth linewidth of 25 mHz<\/li><li>possibility of obtaining mode-resolved spectra with a finesse of 4,000<\/li><li>capability of coherent averaging of &gt; 400,000 interferograms<\/li><li>feasibility for kHz-scale spectral resolution in a comb-tooth scanning mode<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-4e387b4 elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"4e387b4\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-25afb4a\" data-id=\"25afb4a\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-a2ff689 elementor-widget elementor-widget-image\" data-id=\"a2ff689\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1704\" height=\"1008\" src=\"https:\/\/www.creol.ucf.edu\/mir\/wp-content\/uploads\/sites\/7\/2019\/07\/DCS_1.png\" class=\"attachment-full size-full wp-image-833\" alt=\"\" srcset=\"https:\/\/www.creol.ucf.edu\/mir\/wp-content\/uploads\/sites\/7\/2019\/07\/DCS_1.png 1704w, https:\/\/www.creol.ucf.edu\/mir\/wp-content\/uploads\/sites\/7\/2019\/07\/DCS_1-300x177.png 300w, https:\/\/www.creol.ucf.edu\/mir\/wp-content\/uploads\/sites\/7\/2019\/07\/DCS_1-768x454.png 768w, https:\/\/www.creol.ucf.edu\/mir\/wp-content\/uploads\/sites\/7\/2019\/07\/DCS_1-1024x606.png 1024w\" sizes=\"(max-width: 1704px) 100vw, 1704px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Fig. 1.
