    "abstract": "Intracavity laser absorption spectroscopy (ICLAS) with an evacuated Cr2+:\nZnSe laser is performed with a high-resolution time-resolved Fourier transform\ninterferometer with a minimum detectable absorption coefficient equal to 4 10-9\ncm-1 Hz-1/2 in the 2.5$\\mu$m region. This represents the extreme limit\npresently reached in the infrared by ICLAS with Doppler limited resolution. The\nbroad gain band of the crystal allows a spectral coverage at most equal to 125\nnm, wide enough to see entire vibration bands. Weak CO2 bands observed up to\nnow only in the Venus atmosphere are recorded for the first time in a\nlaboratory. H2O detection limit down to 0.9 ppbv is also demonstrated.",
