For recording the far field of 1.06 μm wavelength laser beam with an array camera, and using film to record the array spot diameter, it is difficult to read the spots diameter exactly and also affected by the developing condition. However, there are no such problems if the ultraviolet oscilloscope (UO) paper is used instead of the film. Using the UO paper to record the array spot diameter, the measured beam divergence (at 70% energy) fluctuation is less than 10%, and the energy (at mean divergence) fluctuation is within 5%.
