Abstract: The structures for confining or guiding high frequency electromagnetic radiation have surfaces facing the radiation constructed of high temperature superconducting materials, that is, materials having critical temperatures greater than approximately 35.degree.K. The use of high temperature superconductors removes the constraint of the relatively low energy gaps of conventional, low temperature superconductors which precluded their use at high frequencies. The high temperature superconductors also provide larger thermal margins and more effective cooling. Devices which will benefit from the structures of the invention include microwave cavities, millimeter-wave/far infrared cavities, gyrotron cavities, mode converters, accelerators and free electron lasers, and waveguides.

Abstract: A gas laser adapted to produce laser radiation in the far infrared region of the electromagnetic spectrum, but adapted, as well, to produce radiation in the infrared, the near infrared, the millimeter and the microwave regions. The laser employs a zig-zag pumping scheme which serves to excite the gas uniformly and thus enhance transfer of pump energy into laser energy.
