We present a new method for fabrication of Yb3+-doped photonic crystal fiber(PCF),namely the nonchemical-vapor-depositoin process.Using the solution doping technique,SiO2,YiCl3,AlCl3 and K2CO3 were mixed in water.After evaporation and dying,the well-mixed material was obtained.High concentration Yb3+-doped quartz glass was fabricated by high-temperature melting over 2 000 ℃.The fiber perform was fabricated by stack-capillary method with the Yb3+-doped quartz glass as the core.The fiber perform w...
