Abstract :
An Er-doped fiber amplifier with a flattened gain spectrum is obtained by incorporating the amplifier into a ring laser and making use of inhomogeneous broadening at 77 K. The results indicate several potential benefits for doped-fiber material systems that are inhomogeneously broadened at room temperature.<>
