激光功率的量测是半精出测量,精出度一般超过去5％就算不的了,要超过1％则非常困难,激光功率的量测是辐射能量及功率量测的一部分,辐射能量及功率的量测已进行了许多年的研究与发展。激光功率的量测有其有利的一面,即单色性好,谱线很窄;但亦有其较难的一面,即能量出度大,比较其中在小面积上。 Laser power measurement is semi-precise measurement, the accuracy of more than go to 5% even if not, to more than 1% is very difficult, the laser power measurement is part of the radiation energy and power measurement, radiation energy and Power measurement has been carried out for many years of research and development. Laser power measurement has its positive side, that is, good monochromatic, spectral line is very narrow; but also its difficult side, that is, a large out of energy, more in which a small area.
