摘　　要：依据热释电原理，设计并研制了一种新型的高灵敏、快响应毫米波激光能量探测器。分别在不同工作频率下对器件进行能量标定，并给出主要性能参数。其灵敏度达几十ｍＶ／μＪ，比传统器件高４～５个量级；时间响应小于１μｓ，响应速度提高６～７个数量级。将该能量计应用于拉曼自由电子激光器检测系统，成功地测定了输出毫米波激光脉冲的典型参数。Boing on pyroclectric theory, a novel millimeter wave ther enetgy detectot withhigh sensitivity and fast response has been proposed and designed. We calibrated it atdifferent operating frequencies separately. Its main propetty Parameters have been given.Sensitivity of this energy meter is about several ton mV/μJ, which is four to five ordershigher thsn traditional detector. Its time response is less than 1 μs.The speed of response hasbeen improved by six to. seven orders.This energy meter has been used in detedive systemof Raman free-electron laser. We successfully measured the typical parameters of the outputmillimeter wave laser pulse.
