Paper Abstract

The feasibility of an optical fiber amplifier as a booster amplifier for transmitter-terminals of free-space coherent laser communication systems has been investigated. To enhance the amplifier's efficiency and reliability in a harsh space environment a new pumping-scheme has been analyzed and demonstrated in an experimental set-up. The amplifier features efficient multiple serial coupling of the pump light into the multimode core of the double-clad fiber by using directional Y-couplers. Special attention has been paid to fiber-geometry, pump light absorption efficiency in the neodymium-doped single-mode core and the attenuation of pump and signal light.
