摘要：

Cr4+:YAG crystal has been shown an exceptionally successful ultra broad-band amplified spontaneous emission light source that fully cover 1253-1530 nm range (3 dB bandwidth up to 265 nm). Keeping in mind that the amplified spontaneous emission of Cr4+: YAG is proportional to the concentration of Cr4+ ions. The Cr4+ ions are replenished using an electron-gun to deposit CaO on the source rod circumference under annealing treatment at 1350 degrees C. The laser-heated pedestal growth method was employed to re-grow the Cr4+: YAG single-clad crystal fiber. The doped concentration of CaO can be in-diffuse and it can serve as charge compensators to enhance the concentration of Cr4+ ions. The experimental results indicate that the Cr4+ concentration of Cr4+:YAG crystal fiber can be raised by a factor of 196 %.
