The problem of producing high-current electron beams with relatively small transverse sizes and small velocity spread is more than a hundred years old. The continuous improvement of near ultraviolet electromagnetic radiation sources (lasers with harmonics generators) allows improving the parameters of existing electron guns. This paper discusses some problems in the development of electron guns with photocathodes and considers possible ways of using laser photocathodes in the electron guns at the Budker INP SB RAS.
