【摘要】 针对输出功率数千瓦的连续波激光能量测量需要,研制了一种量热式高能激光能量探头。该探头主要由高纯石墨激光能量吸收体、测温热电偶、绝热陶瓷等组成。重点介绍了探头的研制和通过探头温升回推激光能量的计算方法研究,以及探头测量标定工作。所研制的能量探头耐受激光破坏能力强、结构紧凑,可以组装成阵列,用于大面积高能激光束的能量分布测量。更多还原

【Abstract】 A calorimetric detector is developed for measuring energy of continue wave laser with thousands of kilowatts power output.The calorimetric detector consists of energy absorbing graphite,thermal-couple and adiabatic ceramic part.In this paper,the design of the detector structure,the study of energy processing method in measuring high energy laser and the energy measurement experiment are described.The results show that the calorimetric detector has compact size and can endure high intensity laser irradiation,so it can be integrated into the large array for the measurement of energy distribution of high energy laser beam.更多还原
