The possibilities of using a fiber laser with a femtosecond duration of radiation pulses in the manufacture of miniature thermionic cathodes made of 50 μm of tungsten-rhenium foil are shown. The cathode assembly, consisting of a heater and a core, is made in the form of a solid structure with an oxidecoating applied by ion-plasma sputtering. The emission characteristics of the cathode are presented.
