【摘要】 本文介绍了用粗糙面作为漫反射面的水冷式积分球功率计。经标准能量计标定,具有响应时间快(10^-1秒)、重复性好（优于1%）、可测激光功率范围大（数瓦—千瓦）等特点。该功率计标定误差小于±5%,测量激光输出时,与国家标准大功率计之差在1%以内。更多还原

【Abstract】 A water-cooled integrating sphere laser power meter, using metallic rough surface for its diffuselly reflecting surface, has been described in this paper. The power meter is calibrated by a reference energy meter and has the following special advantages: fast response (10^-1sec), better reproducibility （<1%） and wide measuring range （from 1 to 10³ W）.The resulting difference between the meter and national standard high power meter in measuring the same laser output is within 1%.更多还原
