Abstract
Highly efficient laser sources are required for deep space optical telecommunication. This paper investigates the efficiency components for pulsed diode pumped solid state laser transmitters and determines the overall wall-plug efficiency applicable to a space-borne system. Thermal control of the pump diodes is critical to achieving optimum photon efficiency. Hence, a thermal model involving either a thermo-electric cooler or loop heat pipes is applied to the efficiency calculations. The electro-optical conversion efficiency for an optimized bulk design is expected to be up to 28% with the overall wall-plug efficiency being in the 12 - 16% range depending on the radiator temperature. A fiber based master-oscillator power-amplifier design is also investigated with passively cooled pumped diodes and promises high efficiency operation. Preliminary results from an evaluation model are also discussed.
