| 摘 要： | 以Ar^＋Kr^＋激光器、He—Ne激光器和半导体泵浦激光器作为光源，利用激光稳功率装置以及闭环机械制冷型低温辐射计，校准了硅陷阱探测器的绝对光谱响应率。在硅探测器的光谱响应范围400-1100nm内，选择476．1nm、488nm、514．7nm、521nm、568nm、632．8nm、647．1nm、1064nm共8条谱线进行了实验研究。实验数据表明，绝对光谱响应率的测量不确定度为可见光波段优于0．02％，1064nm波长点优于0．03％。

| Abstract: | The absolute spectral responsivity of the Si trap detector is calibrated by laser intensity stabilizer and closed loop refrigeration cryogenic radiometer with Ar^＋ Kr^＋ laser, He Ne laser and PDSS laser. Eight wavelength laser beams of 476.1 nm, 488 nm, 514.7 nm, 521 nm, 568 nm, 632.8 nm, 647.1 nm and 1 064 nm, vary from 400-1 100 nm, are cho sen for the calibration experiments. The results indicate that the absolute spectral responsivity uncertainty is better than 0.02% in visible light wave band, and 0.03% at 1 064 nm. |
