nLIGHT proposes the development of a 10 kW power amplifier with a predicted power conversion efficiency of approximately 45%. The 10 kW power amplifier will be based on nLIGHT's high power, high efficiency, narrow-linewidth fiber coupled lasers diode modules. We will utilize custom fused fiber combiners to combine the pump modules in an efficient manner, enabling the pumping of next-generation fiber laser systems.
