Abstract

The calibration method using high-power halogen tungsten lamp as calibration source is very fit for calibration of high-energy laser energy meters. However, high-power halogen tungsten lamps after power-off still reserves much residual energy and continually radiates energy. The radiation efficiency of the halogen tungsten lamp after power-off can be quantitatively measured by a fast response radiation detector. The results show that the halogen tungsten lamp's radiation efficiency was improved with power-on time, but did not change under constant power-on time/energy. All the tested halogen tungsten lamps reached 89.3% of radiation efficiency at 50 s after power-on. After power-off, the residual energy in the halogen tungsten lamp gradually dropped to less than 10% of the initial radiation power, and the radiation efficiency changed with time. The final total radiation energy was decided by the halogen tungsten lamp's radiation efficiency, the radiation efficiency of residual energy, and the total energy consumption. The measuring uncertainty of total radiation energy was about 2.4% (k=2).
