Abstract: A semiconductor laser CRT for driving at room temperature, whose target is pumped by an electron beam, in which a laser target is fixed to a beaker-shaped transparent glass support plate, and the glass support plate is sealed with a glass bulb using fused frit glass. Accordingly, there is no cracking of the glass bulb due to a difference in thermal expansion or destroying of a sustained airtight vacuum.

Abstract: A laser cathode ray tube (laser-CRT) is provided. The laser-CRT includes a connection ring connected to an end portion of a glass bulb where an electron gun is installed, a disk having a single-crystal for generating laser beams when electron beams emitted from the electron gun are input, a support ring connected to the disk and the connection ring, and a junction layer interposed between the support ring and the disk, having at least two metal thin films which have been pressurized and heated, to connect the support ring and the disk to each other.
