苗昕扬, 彭 雪, 路婉婷, 詹洪磊, 赵 昆 . 利用量热型激光功率计测量脉冲激光能量的实验研究[J]. 大学物理, 2020 , 39(12) : 32 -35 . DOI: 10.16854 / j.cnki.1000-0712.200026
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.
