Abstract

Power scalability of fiber lasers, today, is from few mW to several kW in CW operation and tens of kW in pulsed operation. The wide range of power is possible due to various configurations of the fiber laser system. One such configuration is Master Oscillator Power Amplifier (MOPA), the topic of interest of our paper. We explain the design aspects of MOPA and discuss optimization methodology for MOPA based fiber lasers. We propose optimization, under co-directional pumping, of pump laser, seed laser and the fiber length. We have focused on the state of art technologies considering Ytterbium doped double clad single mode Nufern fiber.
