For high power fiber lasers, codoping with Al, P or both is necessary to prevent rare earth (RE) clustering in the silica network of the laser active core material. Here, we present a complementary infrared (IR) based multispectral method combined wi

In this paper we will discuss the influence of atmosphere pressure microwave plasma on the background loss and the radial distribution of several dopants in specialty, especially rare-earth (RE) doped, preforms and fibers for high power application.

The intensities of the Fe L lines/bands l = L3M1, η = L2M1, α1,2 = L3M4,5, β1 = L2M4, and β3,4 = L1M2,3 were measured for pure Fe and Fe3O4 using a TAP crystal as the dispersing element. The energy of the exciting electrons, E0, was varied in the

The electron excited N-series lines N4N6 and N5N7 of the element 74W were studied using both energy dispersive (ED) and wavelength dispersive spectrometry. In ED spectra these lines appear as one unresolved peak N4,5N6,7 at approximately 217 eV. The

The M spectrum of the element uranium was reinvestigated by using both high-resolution wavelength dispersive (WD) spectrometry as well as energy dispersive (ED) spectrometry. Thereby we observed relative intensities that deviate from data in the lite
