Electron beam pumped pulsed ultraviolet emitter (~ 300 nm) based on CaF2

Abstract

The parameters of radiation of fluorite CaF2 pumped by pulsed electron beam are presented. UV radiation at a wavelength of 300 nm, a pulse power of up to 1W at an electron energy of 39 keV, a beam current of 60 mA with a pulse duration of about 200 ns have been obtained. It is shown that the output radiation power is independent of temperature in the range of 25–100 ° C.
