LASER CATHODE-RAY TUBE Russian patent published in 1995 - IPC

FIELD: laser technique. SUBSTANCE: two-dimensional scanning CRT has evacuated envelope, electron gun with beam control system, and laser target in the form of plain- parallel semiconductor plate whose opposing surfaces have mirror coatings one of which is blind and other semitranslucent. Laser target is provided with conducting substrate on blind coating side and component providing electric contact between semiconductor plate surface facing electron gun and substrate; electron gun and its control system are located on semitranslucent mirror coating side and placed at certain angle to semiconductor plate surface. EFFECT: 30 and 46 per cent gain in efficiency and radiating power as compared to prototype; 1.5 orders of magnitude lower level of X-rays on laser target side. 4 cl, 1 dwg
