Abstract

This article describes a test method for the pulsed laser beam divergence angle. Pulsed laser focused through the imaging optical system, the light spot formed on the CCD camera and image analysis by an image of the spot, the spot diameter is obtained, to calculate the value of the divergence angle of the laser beam. Experimental results show that this method can be more accurately measured slight angle high-energy pulsed laser beam divergence angle of value.
