The Stark splitting properties of Yb3+atroom temperature in phosphate laser glass werestudied.To enlarge the Stark splitting level,SiO2 as structure formers was added to the simple composition of 60P2O5-7.5Al2O3-15K2O-17.5BaO-1Yb2O3.Detailed Stark splitting manifoldswere obtained by Lorenz fitting of thecorresponding absorption and emission spectrum.The addition of SiO2 influences the Stark splitting of Yb3+intensely,results show that all of the samples possess larger 2F7/2 overall Stark splitting which will trend to operate close to a quasi-four-level scheme and,so that it can reduce the serious thermal blocking problems in some degree.
