Abstract

In high power laser system, continuous phase plate (CPP) is used as a beam smoothing element. Different from traditional plane or spherical elements, the surface of CPP is more complex. Since the surface information with mid-spatial-frequency of a CPP cannot be treated as a kind of noise, so it is difficult to test and analyze the surface quality by ordinary interferometer. The stitching method is used to test CPP. The basic principle and technological process of the test are introduced. The surface shape of a CPP is recovered successfully by using this method.
