Abstract

In this paper, a testing system is introduced to monitor the beam quality of a laser beam propagating over a long distance. The system consists of a large aperture optical system, a high sensitivity receiving system, a fast signal processing circuit and so on. The laser beam quality propagating 10km can be tested, and the two-dimensional energy distribution, pre-mirror energy density, centroid coordinate and other parameters can be obtained.
