Abstract

Highly doped with ytterbium (up to 20 wt% of Yb₂O₃) Er-Yb aliminosilicate glass core fibers have been fabricated and thoroughly investigated. It has been discovered that in a particular condition the lasing properties of both Yb and Er ions can be nearly completely suppressed. Due to a very high Yb ions absorption in the 900-1000 nm range (~ 3000 dB/m at 915 nm) all together with low background losses the developed glass matrix is very promising for such applications as pump isolation in fiber lasers as well as spectral and mode filtering using highly absorbing glass dopants.
