Abstract To improve the quality of laser-induced breakdown spectroscopy, flat-mirror device was proposed. The effects of flat-mirror device on the radiation characteristics of laser-induced plasma were studied. The experimental results showed that when the device consisted of three flat-mirrors placed around the plasma, the spectral line intensity of Mg, Fe, Ba, Ti and Al increases by about 116.2%, 96.43%, 90.93%, 102.1% and 98.57% than that without flat-mirror device, and the signal-to-noise raises by around 39.17%, 32.48%, 38.07%, 39.95% and 21.30%,respectively. By measuring the plasma parameters,the mechanism of the radiation enhancement obtained with the device consisting of three flat-mirrors was explained. This method was an effective way to improve the detection capacity of LIBS.
