激光诱导击穿光谱（LIBS）技术的应用受到了激光辐照引起的陶瓷微片激光性能退化的限制。通过陶瓷和单晶（SC）的光谱比较得出的陶瓷的热处理，恢复恶化的性能。光谱中的吸收增加的γ射线照射，这是高于陶瓷的SC在红外辐射区域。虽然吸收量通过加热而减少，并且通过冷却陶瓷而增加，但是对于SC没有观察到显著的热效应。研究了辐照对陶瓷激光性能的影响，并通过加热的方法很好地恢复了激光脉冲能量损失。由于加热不会使射束轮廓恶化，从而影响LIBS效率，因此该过程在恢复减弱的LIBS信号方面是有效的。虽然加热减少了产生的脉冲的数量，影响了突发模式的测量，减少恢复增加泵浦激光功率。由于单脉冲和多脉冲模式测量的LIBS信号的辐射引起的恶化被很好地恢复，该程序被认为是有效的LIBS系统使用辐射敏感陶瓷的应用，特别是在恶劣的辐射环境中。
The radiation-induced deterioration of ceramic microchip laser properties limits the applications of laser-induced breakdown spectroscopy (LIBS) systems. The deteriorated properties were recovered through thermal treatment of ceramics as derived by the spectroscopic comparison of ceramics and single crystals (SCs). The absorption in spectra was increased by gamma rays irradiation, which was higher for the ceramics than for the SCs in the infrared radiation region. Although the amount of absorption decreased by heating and increased via cooling ceramics, no significant thermal effects were observed for the SCs. The effects of irradiation on the laser properties of ceramics were examined, and the laser pulse energy loss was well recovered via heating. Because 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, affects the burst-mode measurement, the reduction was recovered by increasing the pump laser power. Because the radiation-induced deterioration of the LIBS signal for single-pulse and multiburst mode measurements was well recovered, the procedures are considered effective for the application of LIBS systems using radiation-sensitive ceramics, particularly in harsh radiation environments.
