Blue and green up-conversion in ZBLAN Tm3+Yb3+-codoped glasses pumped with LD 970-nm laser

摘要

The quality of synthesized ZBLAN:Tm$+3$PLU$/,Yb$+3$PLU$/ glasses is analyzed and an efficient up-concentration in the blue and green light of Tm$+3$PLU$/ containing different concentration ratio of Tm$+3$PLU$/:Yb$+3$PLU$/ demonstrated under LD 970 nm pumping. The up-conversion process of Tm$+3$PLU$/ in ZBLAN:Tm$+3$PLU$/,Yb$+3$PLU$/ glasses are presented. The up-conversion in green can be limited restrained by the concentration of Yb$+3$PLU$/.
