Luminescent optical fibres are one of the most important photonics elements as they allow to construct high power fibre lasers and different unique optical sources in the broad range from UV to IR. The most important requirements cover efficient luminescence core materials and easily pumped optical fibre constructions. Depends on the applications the variety of optical fibres have been proposed based on glasses and polymers. In the paper some recent constructions developed in Bialystok Photonics Group have been shown. Full Text: PDF ReferencesA. Zajac, D. Dorosz, M. Kochanowicz, M. Skórczakowski, J.

A possible relationship between the hot prominence transition sheath, increased internal turbulent and/or helical motion prior to prominence eruption and the prominence eruption (“disparition brusque”) is discussed. The associated darkening of the filament or brightening of the prominence is interpreted as a change in the prominence’s internal pressure gradient which, if of the correct sign, can lead to short wavelength turbulent convection within the prominence. Associated with such a pressure gradient change may be the alteration of the current density gradient within the prominence. Such a change in the current density gradient may also be due to the relative motion of the neighbouring plages thereby increasing the magnetic shear within the prominence, i.e., steepening the current density gradient. Depending on the magnitude of the current density gradient, i.e., magnetic shear, disruption of the prominence can occur by either a long wavelength ideal MHD helical (“kink”) convective instability and/or a long wavelength resistive helical (“kink”) convective instability (tearing mode). The long wavelength ideal MHD helical instability will lead to helical rotation and thus unwinding due to diamagnetic effects and plasma ejections due to convection. The long wavelength resistive helical instability will lead to both unwinding and plasma ejections, but also to accelerated plasma flow, long wavelength magnetic field filamentation, accelerated particles and long wavelength heating internal to the prominence.
