The sensitive optical detection technique of cavity ringdown spectroscopy is extended to the wavelength range 197–204 nm. A novel design narrowband Fourier-transform-limited laser is used, and the technique is applied to gas-phase extinction measurements in CO2 , SF6 , and O2. Further demonstration of the system capabilities is given in high-resolution recordings of the Schumann–Runge (0,0) , (1,0) , and (2,0) bands in O2.
