100W optical amplifier for 10 channel laser communication system with enhanced wall-plug efficiency in the 1µm wavelength range
An important aspect of optical satellite communication technology is the power consumption of the laser systems. Therefore, an enhanced wall-plug efficiency of the optical amplifier is needed. We present an optical amplifier for a WDM optical communication system with an enhanced wall-plug efficiency. The desired efficiency of more than 30% can only be achieved through fiber technology. Combining the experiences of in-house manufactured optical fiber components and of laser developments for space applications, an all-fiber amplifier solution was designed. Each of the 10 channels can be efficiently amplified up to a total power level of 100W in the 1µm wavelength-range.
