Abstract :
In this study, we investigate the possibilities of Yb3+-Tb3+ cooperative energy transfer process which enable the 0.98 μm pumping for Tb3+ ions using various host glasses. The energy transfer efficiency as high as 60plusmn11 % was observed for the first time in a borosilicate glass and it was found out that Tb3+-Yb3+-codoped borosilicate glass was a promising candidate for the 0.54 μm band laser medium pumped at 0.98 μm.
