The BEPCII storage ring adopts two 500 MHz superconducting cavities (SCC). Each one is equipped with a 500 MHz input power coupler. The coupler is to feed 150 kW power in continuous wave (CW) mode wit...
High power conditioning of the input coupler for BEPCII superconducting cavity has been performed. After room temperature conditioning, the RF power of 150 kW with continuous wave at standing wave mo...
We report on bottom-emitting vertical-cavity surface-emitting lasers (VCSEL’s) and laser arrays providing high output powers in the 980-nm wavelength regime. Single devices with active diameters of 50...
A diffusion-cooled CO2 laser using a coaxial waveguide is investigated theoretically. The resonator extracting the laser beam consits of two annular plane mirrors enclosing the two ends of the wavegui...
