| Abstract: | Glass-clad Cr4+:YAG crystal fiber is demonstrated by a codrawing laser-heated pedestal growth method. As much as 2.45 mW of superwideband amplified spontaneous emission (ASE) is generated in the optical fiber communication band with a 3-dB width of 240 nm. The simulation indicates that the ASE power could be in excess of 20 dBm for a 5-microm-diameter core at a pump power of 2.5 W. |
