Abstract:
In this paper，a method is proposed to measure the laser energy of the narrow pulses by using a thermal power meter. The laser response is measured at different repetition frequencies. The results suggest that the calorimetric laser power meter can achieve heat balance when the frequency is higher than 8 Hz and the interaction time between the laser and the probe is not less than 4 s. The average energy of a single pulse laser can be calculated by the indicator.
Key words: pulsed laser, calorimetric power meter, average energy, epetition frequency
