摘要
文章介绍了由有色光学玻璃组成的窄带的测量3W以内激光的光电型功率计,具有杂光小、均匀性好、线性好、时间常数小等特点。已研制了测量473nm、532nm、594nm、635nm、671nm、808nm、980nm、1064nm的光电型瓦级激光功率计。测试结果表明:线性比较好,均匀性误差在7‰以内,杂光小于1μW,重复性误差小于7‰,长期稳定性误差小于8‰。
The photoelectric power meters, which are made of color optical glass to measure the output power up to 3W with narrow bandwidth, are introduced. They have the advantages of small stray light, good uniformity, excellent linearity, fast time respond constant and etc. We already study of manufacturing the photoelectric laser power meters at W-class measuring 473nm, 532nm, 584nm, 635nm, 671nm, 808nm, 980nm, 1064nm. The testing results show that the linearity is good, the uniformity error is within 7‰, the stray light is smaller than 1μW, the repeatability error is within 7‰, and the long stability error is within 8‰.
