利用LiTaO_3和LiNbO_3晶体对某些波长激光强烈吸收的特性,研制了一种快响应平面型热电探测器。本文叙述该器件的原理、材料选择、制作工艺和性能,并对它在单片热电阵列方面的发展前景作简单讨论。

A new type fast-response detector is recommended. This pyroeleotrio detector is made of LiTaO3 and LiNbO3 crystals, having very strong absorptive characteristics for laser at certain wavelength. In this paper, the consideration in device design, the selection of materials, the fabrication and performance of such device are described and finally, its prospect for the monolithic pyroelectrio array is briefly dissoused.
