热释电材料作激光能量探测器兼有热元件和光电元件的优点。作为激光能量功率测量多用钽酸锂、TGS(硫酸三甘钛)、SBN(铌酸锶钡)。对PZT(锆钛酸铝)类陶瓷材料研究较少。它们的热释电系数虽比钽酸锂低,但价格便宜,易于获得。我们对几种PZT类材料(PZT-4,5,8型)及PMN(铌锰锆钛酸铝)、PSN(铌锡锆钛酸铝)等作了初步研究。结果表明PZT-4和PSN灵敏度较高,每mJ输入有70mV以上的峰压输出,可满足一般应用需要。用网状背电 Pyroelectric materials for laser energy detectors both the advantages of thermal components and optoelectronic components. As a laser energy power measurement of lithium tantalate, TGS (thioglycolic acid), SBN (barium strontium niobate). PZT (aluminum zirconium titanate) ceramic materials less research. Although their pyroelectric coefficient than lithium tantalate low, but the price is cheap, easy to get. We conducted a preliminary study of several PZT-based materials (PZT-4, 5, and 8) and PMN (niobium-manganese-zirconium titanate) and PSN (niobium- The results show that the sensitivity of PZT-4 and PSN is high, and the peak output of more than 70mV per mJ input can meet the general application needs.
