FIELD: electrical engineering.
SUBSTANCE: invention relates to electronics, more specifically to laser electron-beam devices (LEBD), used in information display systems and medical technology, particularly in scanning optical microscopy. The laser electron-beam projector contains an electron gun with electron-beam focusing and deflection systems and a laser target, consisting of monocrystalline semiconductor zinc oxide nanorods standing on a substrate at an angle of not more than 10° to the vertical, where the said nanorods have diametre equal to 100-500 nm and length equal to 5-100 diametres. The free ends of the nanorods have reflecting mirrors.
EFFECT: reduced laser generation voltage and increased operating temperature.
