An ytterbium-doped photonic bandgap fiber amplifier operating at the long wavelength edge of the ytterbium gain band is investigated for high power amplification. The spectral filtering effect of the photonic bandgap efficiently suppresses amplified spontaneous emission at the conventional ytterbium gain wavelengths and thus enables high power amplification at 1178 nm. A record output power of ...

The magnicon is a RF power source with circular beam deflection [1] invented in the 1980's at Budker INP. The first magnicon with the power of 2.6 MW and efficiency of 73% at 915 MHz was built and tested in the pulse of 30 μsec in 1985 [2]. The second magnicon was developed as a prototype RF source for a linear collider. In order to achieve power of more than 50 MW at 7 GHz, the tube was built ...

Solid-state power amplifiers at W-band (75 110 GHz) are attractive for the generation of local-oscillator (LO) power for super-heterodyne receivers operating at sub-millimetre wave frequencies, as needed for example in future space instruments for Earth observation. Apart from space applications there is a growing interest for these devices in for example millimetre wave imaging, communication ...
