In this work, double_clad, single_mode Nd 3+ _doped and Yb 3+ _doped phosphate glass fibers were prepared. CW laser at 1.053 μm with output power of 8.36 mW was obtained at room temperature by using a 800 nm LD as a pumping source of Nd 3+ _doped fiber. CW laser at 1.067 μm was also observed at room temperature by using Ti-sapphire laser at 930 nm as a pumping source of Yb 3+ _doped fiber. The fluorescence properties as a function of concentration of rare earth ions were investigated in some Nd 3+ _, Yb 3+ _and Er 3+ _doped, as well as Yb 3+ /Er 3+ _codoped phosphate and fluoroaluminate glasses system. It is found that some rare_earth doped glasses, such as Nd 3+ _doped tetraphosphate glass, Yb 3+ /Er 3+ _codoped tetraphosphate glass and fluoroaluminate glass are the promising materials for microchip laser.
