Abstract

Continuous need for short-wavelength light sources operating in the UV and visible spectral range, combining the advantages of compact size, high efficiency and low cost of production results in dynamic development of semiconductor and miniature solid state lasers. Among others, the up-conversion fiber lasers are continuously considered as one of the promising candidates, which in turn stimulates the development of new optically active materials for such applications as well as investigation of new phenomena in already known materials. In this work we present our recent investigations of the up-conversion phenomena in erbium doped fluorozirconate glasses. The unique set of the bulk samples, with active dopant concentration ranging from 500 ppm up to 60000 ppm was carefully characterized with respect of their luminescent properties in the UV-VIS spectral range, under direct and up-converted excitation. In particular - the concentration dependent emission spectra and fluorescence dynamics profiles were measured, enabling discussion of possible up-conversion pathways and optimization of dopant levels and excitation conditions applicable to erbium doped fibers based on these glasses. What is specifically interesting, apart from a typical laser diodes also a pressure-tuned semiconductor lasers were used for the first time as an excitation sources, which enabled experimental determination of optimal pumping wavelengths. #
