Abstract: Aiming at the problem of optical parameter estimation for semitransparent media， an inversion model for optical parameters of semitransparent media exposed to pulse laser irradiation is established. The quantum particle swarm optimization (QPSO) algorithm is adopted to estimate the refractive index and absorption coefficient. The effects of measurement error and thermophysical parameters on the inversion results are analyzed. The relationship between the inversion accuracy and measurement error is revealed by sensitivity analysis. The calculation results show that the established inversion model and the QPSO algorithm can accurately estimate the refractive index and absorption coefficient. Even with measurement error of 10%， the retrieval results still have strong robustness and high accuracy. This study can provide technical reference for obtaining the physical parameters of semitransparent media.
