PURPOSE: A high quality laser screen is provided to enhance brightness of laser CRT by enhancing efficiency of incident electronic beam and reducing accelerating voltage. CONSTITUTION: The laser screen includes a laser target, and a heat removing support member. The laser target includes a first mirror(310), activation layer(320), a second mirror(340) and a metal layer(330,350). The first mirror(310) is formed on a surface contacted with adhesive agent(200), and partially passes through the laser beam. The activation layer is formed on the first mirror(310), and oscillates the laser beam if the electronic beam is entered. The second mirror is formed on the activation layer, and fully reflects the laser beam. The metal layer is deposited between the activation layer and the second mirror. Thereby, the laser screen enhances a brightness by enhancing an efficiency of incidence electronic beam, and reduces accelerating voltage.
