Monolithic GaAlAs/GaAs infrared-to-visible wavelength converter with optical power amplification
IEEE Transactions on Electron Devices, 1981A monolithic wavelength converter has been constructed in the GaAlAs alloy system which comprises a wide gap emitter phototransistor and a double heterojunction (DH) light emitting diode (LED) in a bifacial configuration. The liquid phase epitaxy (LPE)-grown structure is capable of efficiently converting IR light with λ < 870 nm into the red spectral ...

Window-temperature measurements on a high-power gyrotron with an internal, quasi-optical converter
Proceedings of International Electron Devices Meeting, 2002Window-temperature measurements on a double-disc sapphire window have been performed during a series of high-power, long-pulse tests of a 110 GHz, internal-converter gyrotron using a 10-/spl mu/m, infrared camera. Details of the infrared-imaging setup will be discussed and the results obtained will be presented.

A Modular Optical Firing Interface for CERN’s Generic Power Converter Control Platform
2019The power converters group at CERN has developed a third generic converter controller (FGC3) and regulation platform (RegFGC3), capable of controlling any of CERN’s power converters. This platform provides electrical connections to the low-level control elements of power converters, and in some cases a galvanic isolation is required between the ...

Highly Efficient Quasi-Optical Mode Converter for a Multifrequency High-Power Gyrotron
IEEE Transactions on Electron Devices, 2009A highly efficient quasi-optical mode converter with a bandwidth of 38 GHz has been designed and tested. The mode converter combines low-diffraction losses and a Gaussian mode content up to 97% for a set of nine modes in the range of 105 to 143 GHz for a 1-MW CW gyrotron.
