Abstract
A new cavity ring-down spectrometer is designed for the near-infrared spectral region from 745 to 775 nm (12900-13400 cm-1). A test spectrum is presented for the dioxygen rovibrational lines in a narrow spectral range near 13165 cm-1. The sensitivity on the order of 1.7 × 10-10 cm-1 is attained.
