Near-Infrared Detecting Array for High-Energy Laser Measurement
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.
