A narrowband and tunable XUV-laser source, based on harmonic generation of visible laser light, is developed for sensitive and direct absorption measurements. A novel method to monitor and eliminate the fluctuating intensity of this source is developed, which increases the sensitivity for absorption by an order of magnitude. This procedure allows for accurate relative cross-section measurements, demonstrated on selected bands of CO in the wavelength range 95–97 nm.
