Abstract
⺠Continuous-wave cavity-ringdown is able to measure weak optical absorption spectra. ⺠Rapidly swept cavity length or laser frequency initiates optical buildup and decay. ⺠Cavity-excitation time needs to be much shorter than cavity-ringdown decay time. ⺠Highly sensitive noise-equivalent absorption of â¼5 Ã 10â10 cmâ1 Hzâ1/2 is realised. ⺠High-resolution spectra, spanning a wide wavelength range, can be rapidly recorded.
