Spatial filter is an important device of high energy laser. In order to ensure the above functions, it is necessary to keep a certain vacuum inside the spatial filter. The structure of the existing vacuum maintaining filter is complex and inconvenient to debug. In this paper, a space filter based on titanium pump maintenance is designed by improving the design and process of spatial filter. After testing, the vacuum degree inside the filter can reach 10 −5 pa, which can meet the spatial filtering function of high-energy laser beam.
