Abstract
Nd3+ strengthens the Er3+:2.7-\mu m emission 104 times in fluorophosphate glass; in addition, it can also decrease its upconversion effects and the 1.5-\mu m emission accordingly. Cross-relaxation process is the principal transition mechanism in this codoping system. Compared with Er3+ singly doped glass, J-O parameters along with the Arad, \beta, \tau_R values of Er3+ change markedly in Er3+:Nd3+ codoped glass because Nd3+ greatly influences the local environment around Er3+. Results also show that Nd3+ has a good 4I13/2 lifetime quenching effect as well as thermal load reduction ability for Er3+:2.7-\mu m emission.
