摘要： Systems and methods for generating longitudinally modulated (micro-bunched) electron bunches and for generating coherent radiation by the emission from relativistic electrons with a density that is longitudinally modulated (micro-bunched) with a spatial dimension that is significantly below the wavelength of the emitted radiation. The light source includes a high-brightness relativistic electron beam that interacts in a magnetic structure (linear or helical undulator or wiggler) or an electromagnetic structure with a pulse of high-power electro-magnetic wave (modulation laser pulse). The interaction leads to a large energy-modulation of the electron bunch which is transformed into a spatial modulation by an energy-dispersive element that can be the same undulator.

摘要： 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.

摘要： An improved aluminum gallium nitride material is disclosed, which permits the fabrication of improved optical devices such as laser mirrors (1, 2), as well as quantum wells and optical filters. The optical devices are constructed by depositing a buffer layer (7) of aluminum nitride onto a substrate (6), with alternating layers (10, 12, 14, etc.) of AlxGal-xN and AlyGal-yN, where x and y have values of between 0 and 1. Edge emitting lasers (31), surface emitting lasers (52) and quantum wells operating in the ultraviolet region are disclosed. The method of the present invention permits the ability to deposit thin, reproducible and abrupt layers of the improved material to permit the construction of rugged, solid state devices operating at ultraviolet wavelengths.
