%X Searching an efficient algorithm for extracting ring-down time in cavity ring-down spectroscopy(CRDS) is very important.Two kinds of simulated ring-down signals with Gaussian white noises were analyzed using Levenberg-Marquardt(L-M) algorithm and least squares(LS) method,nd the results show that L-M algorithm gives better results,smaller relative error,higher noises immunity and better repetition than LS method.Two kinds of CRDS setups were founded to produce CW and pulsed ring-down signals,experimental dat...
