| Description | Journal: Journal of Physics E: Scientific Instruments The calorimeter used as the primary standard for 0.4-1.1 mu m pulsed laser measurement at NPL consists of a Ni/Cu cone with heating coils and resistance bridge sensing coils around the whole outer surface. An automatic measurement of the light reflected from the cone is made on each shot. The major source of systematic error lies in establishing the difference between the output from a calibration pulse and the output from a laser pulse. Computer modelling of the heat flow was used to predict this difference but still left a residual uncertainty of 0.5%. The overall systematic error at 30 mJ level is +or-0.52% with 0.15% statistical error (SEM over six shots). |
