Abstract

We present model calculations of gain at 1550 nm for Er-Yb double clad amplifiers as a function of pump power, signal input power, fiber length and temperature. The calculated gain is ~ 20 dB for 6W pump for 20 mW input signal at 25 C. More than 10 W of amplified power can be obtained using 8m long fiber with ~ 25 W of pump power. The gain decreases with increasing input signal. We show that a high power Er-Yb co-doped double-clad fiber amplifier also exhibits high gain for Yb transition near 1060 nm. This is not unexpected since the input pump causes population inversion in Yb also.
