Paper Abstract

Since Nd-doped fiber amplifiers could be used as power amplifiers for high data rate optical inter-orbit communications, we have fabricated and studied a square shaped double clad Nd-doped fiber for the 1.06 micrometers amplifier characteristics. The output signal power is not saturated up to 1 watt level using the single frequency broad linewidth signal source. It is, however, saturated at a few hundred milliwatts by a stimulated Brillouin scattering effect using narrow linewidth non-modulated linewidth signal source. The maximum output power of 1.17 Watts is obtained with extraction efficiency of 37 percent from absorbed pump power. The net gain is estimated more than 25dB.
