Paper Abstract

The laser divergence angle is an important parameter of laser beam quality. In order to meet the actual needs of engineering, a method for measuring the laser divergence angle was derived. The laser divergence angle was obtained by measuring the total laser energy and the laser energy behind the aperture. A measuring device was designed for validation. The experimental results showed that the result of the measurement was accurate with an error being smaller than 0.001 mrad . The entire measurement method and the system are simple, easy to operate and can quickly and accurately measure the laser divergence angle. They completely satisfy actual needs.
