    • An electron-beam excitation laser has a laser structure with a light emitter and reflectors on one hand and an electron source on the other hand, wherein at least part of the light emitter or reflectors has a multidimensional photonic crystal structure. An electron-beam excitation laser includes an electron source emitting electrons and a laser structure consisting of a light emitter and reflectors, accelerates electrons from the electron source, and irradiates the electrons to the laser structure to emit a laser beam from the laser structure, wherein the reflectors and/or the light emitter in the laser structure are formed with multidimensional photonic crystals in which dielectrics with different dielectric constants are arrayed in a plurality of directions at periodic intervals, and one of the dielectrics with different dielectric constants may be formed with a light-emitting material.

    • A device for generating electromagnetic radiation including a cathode and an anode. The output port that is integral with the cathode is an electron emitting sheet of material having a low work function for emitting electrons and for a given thickness has a large transmissivity for transmitting radiation. The anode has a target configuration capable of emitting electromagnetic radiation when irradiated by an electron beam. The cathode sheet is supported by a support layer that is selected to be transmissive to the electromagnetic radiation when the cathode sheet must be thin enough to transmit the radiation but is not thick enough to be self supporting. When the support layer is an insulator, electrical connection is made directly to the cathode sheet or to a conducting layer interposed between the cathode sheet and support layer.
    • 一种用于产生包括阴极和阳极的电磁辐射的装置。 与阴极整体的输出端口是发射电子功函数低的电子发射片材,而给定厚度的电子发射片材具有大的透射率用于透射辐射。 阳极具有当由电子束照射时能够发射电磁辐射的目标构造。 当阴极片必须足够薄以透射辐射但不够厚以便自支撑时,阴极片被选择为对电磁辐射透射的支撑层支撑。 当支撑层是绝缘体时,直接将电连接到阴极片或插入到阴极片和支撑层之间的导电层。
