the phenomenological intensity parameters of Er3+ in Er3+, Yb3+: YAG crystals: з2=6
967】10-20cm2, з4=8
809】10-20cm2, з6= 5
620】10-20 cm2 were obtained with absorption spectrum measurement
Strong up-conversion luminescence about 554 and 679nm from laser crystal was investigated in room temperature, when the crystal was pumped by a diode laser at 974 nm, corresponding to 4S3/2℃4I15/2 and 4F9/2℃4I15/2 of Er3+ ions
Dependence of emission on excitation power under 974nm excitation for Er3+, Yb3+:YAG is tentatively explained by energy transfer from Yb3+ ions to Er3+ ions
The intensity of 554 and 679 nm luminescence varied with the pump power in a double logarithmic relation whose index are 1
69and 1
19 order, respectively
The fluorescence lifetime of 2F5/2 level of Yb3+ in codoped YAG is 674レs, lower then msresults of experiment show that Yb3+ ion is a good sensitive agent
