Abstract

An electron beam pumped semiconductor laser includes a semiconductor laser screen and an electron beam source adjacent the semiconductor laser screen. The semiconductor laser screen comprises a transparent single crystal substrate, an electron beam responsive active gain layer on the substrate, and first and second reflective layers. The epitaxial electron beam responsive active gain layer has a crystal structure in alignment with the crystal structure of the substrate, and the first and second reflective layers define a laser cavity through the epitaxial electron beam responsive active gain layer therebetween. The electron beam source generates an electron beam which impinges on the epitaxial electron beam responsive active gain layer thereby generating a laser output. Accordingly, the single crystal active gain layer can be formed on the substrate by epitaxial deposition techniques increasing the performance and reliability of the electron beam pumped semiconductor laser.
