Abstract
In this paper, we conduct a simulation research on the filtering effects of various far-field spatial filters (including pinhole filter and various slit filters) and point out that there are obvious filtering differences among them under some conditions, which are always considered to be basically the same, and explain their formation mechanism. The result has certain significance for the slit filters with excellent performance to be applied in high-power lasers.
