（0.1~100）mW激光功率基准装置以高灵敏度热电堆为传感元件，具有锥腔吸收、孪生补偿、电替代校准的结构，可用精确可测的电功率经过内设的电加热丝进行量值校准和复现，具有响应灵敏度高、光谱响应平坦、光电等效性高、响应度线性等特点，是保存和复现我国（0.1~100）mW激光功率量值和光谱总辐射量值的源头，与俄罗斯光学物理计量研究院双边比对一致性优于0.1%。该基准的量值为激光功率计、辐射功率计、辐射热计、激光探测器响应度的标定和校准提供最高量值依据。The (0.1–100) mW laser power primary standard uses a high-sensitivity thermopile as its sensing element, featuring a structure with cone-cavity absorption, twin compensation, and electric substitution calibration. Its quantity value can be calibrated and reproduced using precisely measurable electric power via the built-in electric heating wire. It features high response sensitivity, flat spectral response, high photoelectric equivalence, and linear responsivity. This standard serves as the primary metrological source for preserving and reproducing the (0.1–100) mW laser power quantity value and total spectral radiation quantity value in China. The consistency of bilateral comparisons between this standard and the All-Russian Research Institute for Optical and Physical Measurements is better than 0.1%. The quantity value of this primary standard provides the highest metrological basis for the calibration of laser power meters, radiant power meters, bolometers, and the responsivity characterization of laser detectors.
