Abstract

We improved our glue splicing method to join silica and fluoride glass fibers. It is now even more robust and stabile with a mean loss below 0.5 dB. Moreover, the splice reflection was reduced to about -42 dB when an index matching gel was used. Pieces of Pr³⁺/Yb³⁺ doped ZBLAN fibers with lengths of 25 cm were connected to silica fibers. In a fiber laser resonator 6 mW of red laser radiation was achieved with the spliced fibers at a pump power level of 144 mW at 845 nm.
