| 内容記述 | The radiation-induced deterioration of ceramic microchip laser properties, which limits the applications of the laser-induced breakdown spectroscopy (LIBS) system, was recovered with thermal treatment as derived by spectroscopic comparison of ceramics and single crystal (SC). Absorption in spectra was increased by radiation, and the increase was greater for ceramics than for SC in the infrared radiation (IR) region. Although for ceramics, the absorption decreased by heating and increased by cooling, no significant thermal effects were observed for SC. The effect of irradiation on the laser properties of ceramics was examined, and the reduced laser pulse energy was well recovered by heating. Since heating did not deteriorate the beam profile affecting the LIBS efficiency, the procedure was effective in recovering the diminished LIBS signal. Although, heating reduced the number of generated pulses, which affects burst-mode measurement, it was recovered by increasing pump laser. Since radiation-induced deterioration of the LIBS signal for single pulse and multi-burst mode measurements was well recovered, the processes are effective for the application of LIBS systems using radiation sensitive ceramics particularly in harsh radiation environments. | |||||
