Spectrum around 190 THz with resolved comb lines, measured within 1860 s. a Entire apodized spectrum across the entire domain of emission of the laser oscillators: more than 200 000 individual comb lines spanning 20 THz are resolved. b Magnified unapodized representation of a. showing the P(7) Doppler-broadened line of the ν1 + ν3 band of 12C2H2 sampled by the comb lines of 100 MHz line spacing. The Doppler full width at half maximum of the P(7) line at 295 K is near 473 MHz. c Magnified unapodized representation of a showing five individual comb lines with with their cardinal sine instrumental line shape
