采用光热/光电阵列相结合的方法，研制了近红外波段高能激光束总能量和光斑时空分布的测量系统。该系统可实现波长范围0.9～1.7 μm、动态范围W/cm2～kW/cm2的激光光斑参数测量，并具有探测光斑面积大和测量不确定度小等特点。通过验证，系统有效探测面积为22 cm×22 cm，空间分辨力为1.1 cm。能量测量不确定度小于10%，功率密度测量不确定度小于15%。该方法可以作为近红外高能激光参数测量的有效手段。

By using the method of combining photo-thermal/photoelectric array, a measuring system of near infrared high energy laser beam and time-space distribution of the spot is developed. The system can be used for laser beam parameter measurement of the wavelength range of 0.9～1.7 μm and the power density range of W/cm2～kW/cm2 with the characteristic of large detection area of spot and small measurement uncertainty. The result shows that the system has the effective sensitive area of 22 cm×22 cm, and the spatial resolution of 1.1 cm. The energy measurement uncertainty is less than 10%, and the power density measurement uncertainty is less than 15%. This method is an available approach for parameter measurement of near-infrared laser beam.
