0.1～100mW激光功率基准与副基准比对
Comparison of 0.1～100 mW Laser Power between Primary Standard and Secondary Standard
摘要
Abstract
To ensure the accurate and consistent transfer of laser power scales,a direct comparison between the primary standard and the secondary standard for 0.1～100 mW laser power was conducted.The comparison was carried out under both broadband uniform irradiation condition and laser beam condition.Excellent agreement was achieved under uniform irradiation condition,with a relative deviation within-0.08%and an En value of-0.08.Under the laser beam condition,the initial relative deviation of the power realizations was-1.64%.The response uniformity of the primary standard and the secondary standard was experimentally investigated,revealing that the secondary reference device exhibited a measurable non-uniformity under laser beam conditions.After correcting the responsivity of the secondary standard based on the response uniformity,the relative deviation decreased to-0.26%.and the En value of-0.25,which achieved an excellent agreement for realization of the 0.1～100 mW laser power primary standard and the secondary standard.关键词
