PURPOSE: A laser CRT is provided to enhance oscillation efficiency of a laser in a cavity with low voltage by compensating split efficiency of energy level which is caused by defects. CONSTITUTION: The laser CRT includes a valve(26), electron gun(29), laser target(23), and a circuit part(33). The inner part of the valve maintains a vacuum state. The electron gun is mounted to an inner part of the tube. The tube is mounted to the valve, and is enlarged. The laser target oscillates a laser beam. The electron beam from the electron gun is landed on the laser target. The circuit part includes an electrode formed on the laser target with a predetermined pattern, and a power-supply device for applying a power to the electrode. The circuit part is mounted to one end of the laser target, and applies a voltage to the laser target. Thereby, the laser CRT enhance oscillation efficiency of a laser in a cavity by compensating a split efficiency of energy level.
