An electron beam pumped laser including a surface-emitting laser faceplate
oriented at a non-perpendicular angle. Embodiments are described in which
a bending coil bends the electron beam, or in which the faceplate is
situated in the direct path of the e-beam emission but with a non-zero
orientation angle. The faceplate may include a substantially opaque
substrate, and an opaque heat-removing structure may be attached to the
substrate to provide high heat transfer, thereby allowing high
electron-beam pumping intensity and providing more light emission from a
smaller package. In some embodiments the partially reflective mirror
comprises a metal layer that has a plurality of openings. Multiple laser
faceplates (e.g., red, green, and blue) may be placed in the same tube,
to provide a continuous light source for projection television. The
substrate may be connected to ground to provide an exit path for
electrons from the laser gain layer.
