Research of Calibration Method for High Energy Laser Energy Meter
|
Abstract:
A new method for calibration of absolute high energy meter is given in the paper.High power lamp is used as calibration light.By measuring the voltage and current on the lamp and decreasing the heat lose of the lamp and transmission lead,light energy emitted by the lamp can be got.A slab energy is designed to shut the lamp in the energy meter,so light emitted by the lamp is totally absorbed by the laser energy meter.According to the output value of the energy meter and the emitted light energy,calibration for high energy meter can be achieved.Calibration experiment is carried to calibrate an absolute calorific high energy laser energy meter by using this method,the uncertainty of the calibration is around 1.5%.
